DEFINITION

Classification: 525/11

Mixed in presence of specified material or a polymerizable composition contains a specified material:

(under subclass 10) Subject matter wherein a polymer derived from a di- or higher ester of a polycarboxylic acid as sole reactant or derived from a polycarboxylic acid or anhydride

and polyhydroxy compound is mixed with an ethylenic reactant in the presence of a specified material which is not a reactant or wherein the polymerizable polyester-unsaturated reactant composition contains a specified material.
