Class Information
Number: 525/37
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > 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 hydroxyl 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 > Polymer derived from polycarboxylic acid or anhydride and polyhydroxy compound is derived from at least two polycarboxylic acid reactants or two polycarboxylic acid anhydrides or mixture thereof > At least one of said polycarboxylic acid reactants or anhydrides contains ethylenic unsaturation > Polymer mixed with unsaturated reactant containing phosphorus atom
Description: Subject matter wherein the unsaturated reactant mixed with the polyester contains phosphorus.
