Abstract:
1. An oligomer consisting of macromolecules of structure I: wherein the oligomer is synthesized by cationic copolymerization of monomer A with a cationically polymerizable monomer B, wherein monomer A has the formula: and wherein in structure I, Z is a moiety derived from monomer B selected from the group consisting of propylene, 1-butene, 1-pentene, 1-hexene, a cyclic olefin, a styrene, a vinyl ether, a benzoxazine, and an oxazoline, L is absent or is a moiety selected from the group consisting of an alkylene, an oxyalkylene, an arylene, and a siloxane linker, and each of m and n is an integer independently having the value between 3 and 10,000, with the further proviso that each and every maleimide group that is present in monomer A remains intact in structure I.
