Hydroxyalkylated high performance curable polymers

A composition which comprises (a) a polymer having terminal end groups and monomer repeat units, at least some of said monomer repeat units having hydroxyalkyl substituents, said polymer having monomer repeat units of the formula ##STR108## wherein x is an integer of 0 or 1, 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 polymer, R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are alkyl groups or substituted alkyl groups, A is ##STR109## or mixtures thereof, B is ##STR110## wherein v is an integer of from 1 to about 20, ##STR111## wherein z is an integer of from 2 to about 20, ##STR112## wherein u is an integer of from 1 to about 20, ##STR113## wherein w is an integer of from 1 to about 20, ##STR114## or mixtures thereof, and n is an integer representing the number of repeating monomer units;

• (b) at least one member selected from the group consisting of photoinitiators and sensitizers, provided that when said second component is a sensitizer, said polymer either (i) has at least some of the hydroxyalkyl substituents thereof replaced with unsaturated ester substituents, or (ii) contains a benzophenone moiety in the backbone thereof;
• and (c) an optional solvent.
