DEFINITION

Classification: 528/271

(under subclass 1) Subject matter under Class 520, ... involving polymers derived from at least one carboxylic acid or carboxylic acid derivative or processes of polymerizing; polymerizable composition containing as a reactant a carboxylic acid or derivative or process of preparing.

(1) Note. A derivative of a carboxylic acid is limited to a nitrile, ester, anhydride, salt, amide, imide, lactam, lactone, and acyl halide.

(2) Note. A carboxylic acid denotes:

(A1) The structure wherein n is one or greater and the C- atom is not double bonded to oxygen, sulfur, selenium, or tellurium, or is not triple bonded to nitrogen.

(A2) The structure wherein n is one or greater, e.g., formic acid when n=1.

(A3) The structure wherein n is an integer, e.g., oxalic acid when n=1.

(B1) The structure wherein n is one or more and the carbon atom bonded to thegroup and the carbon atom single bonded to the oxygen atom of the group is not double bonded to oxygen, sulfur, selenium, or tellurium, or triple bonded to nitrogen. (B2) The structure wherein the atom single bonded to the group is not double bonded to oxygen, sulfur, selenium, or tellurium, or is not triple bonded to nitrogen.

(B3) The structure wherein n is an integer and X is or a derivative as defined in the (1) Note of this subclass.

A carboxylic acid amide denotes:

(C1) The structure wherein n is one or greater and the atom bonded to the group is not double bonded to oxygen, sulfur, selenium, or tellurium, or triple bonded to nitrogen.

(C2) The structure wherein n is one or greater.

(C3) The structure wherein n is an integer and X isor a derivative as defined in the (1) Note of this subclass.

A nitrile for purposes of this subclass denotes:

(D1) The structure wherein n is an integer and wherein the atom is not double bonded to oxygen, sulfur, selenium, or tellurium.

(D2) The structure wherein n is an integer.

(D3) The structure wherein n is an integer and x is or a derivative, i.e., salt, ester, amide, imide, lactam, lactone, anhydride, or nitrile.

A carboxylic acid anhydride denotes: (E1) The structure wherein n is one or more and wherein the carbon atom bonded to the group is not double bonded to oxygen, sulfur, selenium, or tellurium.

(E2) The structure wherein n is an integer, X is or a carboxylic acid derivcative as defined in the (1) Note of this subclass.

(E3) The structure In E1, E2, and E3 the group may be joined together in a ring. An acyl halide of a carboxylic acid denotes:

(F1) The structure wherein n is one or more and wherein the carbon atom bonded to group is not double bonded to oxygen, sulfur, selenium, or tellurium.

(F2) The structure halo wherein n is one or more.

(F3) The structure halo wherein n is an integer and X is or a carboxylic acid derivative as defined in the (1) Note of this subclass.

(G)

A carboxylic acid imide denotes the structure wherein n and x are one or more, as illustrated below. [figure]

(H)

The lactam of a carboxylic acid denotes the structure wherein n and x are one or more as illustrated below. [figure]

(I)

The lactone of a carboxylic acid denotes the structure, illustrated below, wherein x and n are one or more and the carbon atom bonded to the group and the carbon atom single bonded to the oxygen atom of the group are not double bonded to oxygen, sulfur, selenium, or tellurium, or triple bonded to nitrogen. [figure] (J1) The salt of a carboxylic acid denotes the structure, illustrated below, wherein n is one or more and the group and the X component are held together primarily by ionic forces: the carbon atom bonded to thegroup is not double bonded to oxygen, sulfur, or tellurium, or triple bonded to nitrogen. [figure]

(J2) The structure, illustrated below, wherein n is one or more and the group and the X component are held together primarily by ionic forces. [figure]

(J3) The structure, illustrated below, wherein n is an integer. Z is or a derivative as defined in the (1) Note of this subclass and wherein the X component and the component are held together primarily by ionic forces. [figure]

(3) Note. In the above definitions of carboxylic acid and their derivatives, certain compounds may have more than one function (e.g., a lactone is a species of ester, a lactam is a species of an amide). Compounds which are multifunctional are classified on the basis of the first-appearing function provided in the subclass hierarchy.

(4) Note. A polycarboxylic acid reactant for purposes of this subclass requires the presence of at least two carboxylic acid groups. A polycarboxylic acid derivative requires at least one carboxylic acid group and at least one carboxylic acid derivative, or at least two identical carboxylic acid derivatives, or at least two different carboxylic acid derivatives. See (1) Note above for an explanation of the term "derivative".

(5) Note. For purposes of this subclass an anhydride having the general formula, which may be linear or cyclic is considered as being a polycarboxylic acid. A compound having both an anhydride and a free carboxylic acid is considered as being a tricarboxylic acid, e.g. as in the first illustration below, and a compound containing two anhydride groups is considered as being a tetracarboxylic acid, e.g., as in the second illustration, below. [figure] [figure]

(6) Note. An imide is considered as being a dicarboxylic acid derivative.

(7) Note. An organic amine salt of a carboxylic acid has been classified as if it were a mixture of an amine and a carboxylic acid. An organic diamine salt of a dicarboxylic acid where the amine salt-forming groups are identical is considered as being a single amine compound; whereas if the amine groups are different then they are regarded as two amine compounds. Where the compound contains two or more nitrogen atoms bonded to the same or different noncarbonyl carbon atom then they are to be regarded as polyamines.
