DEFINITION

Classification: 528/86

(under subclass 1) Subject matter under Class 520, ... involving polymers derived from a phenol, phenol ether, inorganic phenolate and processes of polymerizing; polymerizable compositions containing a phenol, phenol ether, inorganic phenolate reactant and processes of preparing a polymerizable composition.

(1) Note.

(A)

A phenol for purposes of this subclass requires one or more -OH groups directly bonded to a nuclear carbon atom of a substituted or unsubstituted benzene ring, which benzene ring can be an individual benzene ring or can be part of a polycyclic ring system.

(B)

A phenol ether for purposes of this subclass requires one or more -O-C- groups wherein the oxygen atom of the -O-C- group is directly bonded to a nuclear carbon atom of a substituted or unsubstituted benzene ring and wherein the carbon atom of the -O-C- group is not double bonded to oxygen, sulfur, selenium, or tellurium or triple bonded to nitrogen. The benzene ring may be an individual benzene ring or may be part of a polycyclic ring system. The following examples of phenol ethers are within the definition set out above:

(1) The -O-C- group may itself be part of a cyclic ring system, e.g., , etc.

(2) The carbon of the -O-C- group may be a ring atom of a cyclic or

, etc.,

aromatic ring, e.g.,

(3) The carbon of the -O-C- group may be a terminal carbon atom, e.g.,

or may be the carbon atom of a chain, e.g.,

(C)

An inorganic phenolate is an inorganic salt of a phenol (see phenol (1) above) wherein the hydrogen atom of a -OH

group is replaced by a metal or an inorganic group.

(2) Note. The term phenolic reactant as used throughout this subclass is intended to include the subject matter enumerated in the (1) Note above.

(3) Note. For purposes of this subclass tannin or tannic is considered to be a poly-hydroxy polycyclic carboxy-containing phenol. (4) Note. For purposes of this subclass cresylic acid is considered to be cresol.

(5) Note. For purposes of this subclass coal tar extracts are considered to be an indefinable mixture of ingredients some of which are phenolic in nature and are classified in this area on the basis of the coreactant, if any.

(6) Note. For purposes of this subclass, Cardanol and anacardic acids are considered to be phenols.

SEE OR SEARCH THIS CLASS, SUBCLASS:

1+, for a cashew nut shell liquor containing anacardic acid or Cardanol.

480+, for processes of preparing a polymer not involving a chemical modification of the polymer, by the addition of a material thereto, and for chemically modifying material other than the polymer. Subclasses 480+ also provide for processes of admixing with a broadly claimed nonreactant material.

526, Synthetic Resins or Natural Rubbers,

313, for a polymer derived from an ethylenically unsaturated phenol, phenol ether, or inorganic phenolate as sole monomer or as interpolymer derived from only ethylenically unsaturated reactants wherein at least one of the ethylenically unsaturated reactants contains a phenol, phenol ether, or inorganic phenolate group.
