Abstract:
1. A composition which comprises a crosslinked or chain extended polymer having a backbone of the formula wherein the phenyl groups and the A and B groups can be substituted, wherein x is an integer of 0 or 1 and n is an integer representing the number of repeating monomer units and is at least 5, wherein, when the polymer backbone is of the formula either (a) A is or mixtures thereof, and B is wherein v is an integer of from 1 to about 20, wherein z is an integer of from 2 to about 20, wherein u is an integer of from 1 to about 20, wherein w is an integer of from 1 to about 20, or mixtures thereof, or (b) A is and B is wherein z is an integer of from 2 to about 20, wherein u is an integer of from 1 to about 20, wherein w is an integer of from 1 to about 20, or mixtures thereof, and when the polymer backbone is of the formula A is or mixtures thereof, and B is wherein v is an integer of from 1 to about 20, wherein z is an integer of from 2 to about 20, wherein u is an integer of from 1 to about 20, wherein w is an integer of from 1 to about 20, or mixtures thereof, said crosslinked or chain extended polymer having been formed from a precursor polymer having epoxy groups contained on at least some of the monomer repeat units thereof, said precursor polymer being of the formula wherein “E” is an epoxy group and a, b, c, and d are each integers of 0, 1, 2, 3, or 4, provided that at least one of a, b, c, and d is equal to or greater than 1 in at least some of the monomer repeat units of the precursor polymer, said crosslinking or chain extension having occurred through, linking groups formed by a reaction between the epoxy groups contained on at least some of the monomer repeat units of the precursor polymer and amine groups on an amine curing agent.
