DEFINITION

Classification: 523/500

Process of forming a composition of an ethylenically unsaturated reactant or ethylenically unsaturated polymer admixed with nonreactive material (NRM) and a polyester whose polymer backbone was derived through the direct formation of the ester linkage, e.g., polyethylene terephthalate, polycaprolactone, etc., or product thereof:

(under subclass 1) Subject matter wherein the composition contains an ethylenically unsaturated reactant or ethylenically unsaturated polymer admixed with a nonreactive material (NRM) and a polyester whose polymer backbone was derived through the direct formation of the ester linkage, and must link through the carbonyl group, i.e., -O

(1) Note. Polymerization of di- or higher esters of polycarboxylic acids, lactones, lactides, glycolides, hydroxy-substituted carboxylic acids or derivatives, condensation of polyols with polycarboxylic acids or derivatives and polyketenes all produce polyesters proper for this subclass. Excluded here are those products wherein solid polyester formation does not link through the ester carbonyl

and along the polymer backbone, e.g., polyester urethanes prepared through the condensation of polyhydroxy terminated esters with a polyisocyanate, esterification of polycarboxylic acids or derivatives with polyepoxides, esterification of monomers, or polymers containing plural hydroxyl groups, e.g., pentaerythritol with monocarboxylic acids, or ethylenic polymerization of unsaturated esters.

(2) Note. The polyester can be a solid or a liquid polymer.

(3) Note. Included herein are processes or compositions which are the result of the formation of a polyester in the presence of a NRM and the subsequent blending of an ethylenic reactant or ethylenic polymer therewith.

(4) Note. Where a reaction is indicated between a polyester and an ethylenically unsaturated reactant, such a reaction may occur prior to, concurrent with, or subsequent to the addition of a nonreactive material. For example, the reaction between polyethyleneglycol maleate with dicyclopentadiene and subsequently blended with 2 percent fiber glass is properly classified here.

(5) Note. Unless otherwise indicated, addition polymers derived respectively from mono- and plural-ethylenically unsaturated reactants will be respectively considered saturated and unsaturated. Thus, when blended with a DNRM and an appropriate polyester the composition containing the saturated polymer is not classified here while the unsaturated polymer is.

(6) Note. An ethylenically unsaturated polymer may be one whose unsaturation was retained during or introduced after polymerization, e.g., polymerization of butadiene, transesterification of hydroxy-terminated polyethylene terephthalate with methyl acrylate, dehydrohalogenation of polyvinylidene chloride, etc. SEE OR SEARCH CLASS

10+, for the admixture of an ethylenically unsaturated reactant admixed with either a polyester derived from a saturated di- or higher ester of a polycarboxylic acid as sole reactant or admixed with a polyester derived from a polycarboxylic acid or anhydride with a polyol wherein at least one of the reactants is saturated; and subclasses 242+ for the admixture of an ethylenically unsaturated reactant admixed with the polyester derived from ethylenically unsaturated reactants only.
