DEFINITION

Classification: 525/10

ETHYLENICALLY UNSATURATED REACTANT ADMIXED WITH EITHER (A) A POLYMER DERIVED FROM A SATURATED DI- OR HIGHER ESTER OF A POLYCARBOXYLIC ACID AS SOLE REACTANT, OR (B) REACTION PRODUCT OF ONLY POLYCARBOXYLIC ACIDS OR ANHYDRIDES WITH ONLY COMPOUNDS HAVING AT LEAST TWO HYDROXY GROUPS AT LEAST ONE OF WHICH IS SATURATED AND WHEREIN THE REACTION PRODUCT FORMED IS NOT AFTERTREATED PRIOR TO ADMIXTURE WITH THE UNSATURATED REACTANT EXCEPT WITH A POLYCARBOXYLIC ACID POLYCARBOXYLIC ACID ANHYDRIDE, OR A POLYOL, AND WHEREIN NO SOLID POLYMER DERIVED FROM ETHYLENIC REACTANTS ONLY IS MIXED THEREWITH:

(under subclass 1) Subject matter under Class 520, ... involving a polymer derived from nonethylenic di- or higher esters of a polycarboxylic acid as sole reactant, or the reaction product of only polycarboxylic acids or anhydrides

with only compounds having at least two hydroxy groups, at least one of which is saturated, mixed with at least one ethylenically unsaturated reactant and wherein the polymer or reaction product formed from the di- or higher ester or from the polycarboxylic acid or anhydride and polyhydroxy compound is not aftertreated prior to mixing with the unsaturated reactant except with a polycarboxylic acid, polycarboxylic acid anhydride, or a polyhydroxy compound, and wherein no solid polymer derived from ethylenic reactants only is mixed therein; processes of preparing or reacting the above mixtures and compositions resulting from the mixing or reacting processes.

(1) Note. Included herein are all polyester-unsaturated reactant mixtures defined above except those cases in which the document specified that a mere diester is formed.

(2) Note. Excluded from this subclass is a mixture of a polymer derived from an unsaturated carboxylic acid ester as sole reactant, e.g., diallyl phthalate, diallyl maleate, etc., and an ethylenic reactant.

(3) Note. Excluded from this and the indented subclasses are those unsaturated reactants which have been prereacted and are part of a specified polymer-forming system (e.g., liquid reaction product of unsaturated diisocyanate and a polyol, etc.).

SEE OR SEARCH THIS CLASS, SUBCLASS:

55+, for a solid polymer derived from ethylenic monomers only mixed with the polyester-unsaturated reactant mixture.

242+, for a mixture of ethylenic reactant with a polymer formed of ethylenic reactants only. 418+, for those instances wherein the polyester is treated with reactants other than those specified in the title of this subclass if a solid polymer is formed.

528, Synthetic Resins and Natural Rubbers, for those instances wherein the polyester is treated with reactants other than those specified in the title of this subclass if the polyester is not a solid.
