Synthesis of Novel Copoly(alkyl ether imide)s With Unique Surface Properties
Copoly(alkyl ether imide)s were synthesized for the purposes of tailoring surface chemistry. Alkyl ether oligomers with amine end groups were synthesized from the hydroxyl-terminated species, and subsequently reacted with aromatic dianhydrides and diamines to make the...
