DEFINITION

Classification: 525/167

Polycarboxylic acid or derivative or polyol contains an atom other than C, H, or O; or wherein a polycarboxylic acid or derivative or polyol or condensate thereof is reacted with a reactant containing atoms other than C, H, or O prior to blending with the solid polymer; or wherein a coreactant with the polycarboxylic acid or derivative or polyol contains an atom other than C, H, or O:

(under subclass 165) Subject matter wherein the polycarboxylic acid or derivative or polyol contains an element other than C, H, or O; or wherein the polycarboxylic acid or derivative, polyol or reaction product thereof is reacted with a compound containing elements other than C, H, or O prior to blending with the solid polymerized ethylenic reactant; or wherein the coreactant with the polycarboxylic acid, derivative, or polyol contains an element other than C, H, or O.
