Abstract
Abstract A composition comprising a polymer having a processing temperature of at least 200° and from about 0.1 wt % up to about 30 wt % of crosslinking agent said crosslinking agent comprising a compound of the formula ##STR1## wherein X is hydrogen and Y is ##STR2## and X and Y are substituents on adjacent carbon atoms of A or wherein X and Y together form the imide ring system ##STR3## which is joined to A on adjacent carbons atoms, thereof, wherein A is an aromatic, heteroaromatic, alicyclic, or heterocyclic system or an open chain aliphatic moiety, where R is vinyl, allyl, methallyl or propargyl and wherein R' is hydrogen, C 1 to C 12 alkyl or R and mixtures thereof. Compounds per se and articles manufactured from the above-indicated polymer compositon are also taught.
