DEFINITION

Classification: 525/315

Ethylenic reactant reacted in the presence of a solid polymer substrate derived from reactant containing two unsaturated groups and is devoid of an aromatic group:

(under subclass 313) Subject matter wherein the initial solid polymer derived from a reactant containing at least two ethylenic groups and is free of an aromatic group and which solid polymer is reacted with an ethylenic reactant.
