Partially Hydrolyzed Poly(2-alkyl/aryl-2-oxazoline)s as Thermal Latent Curing Agents: Effect of Composition and Pendant Groups on Curing Behavior.

ABSTRACT: Poly(2-alkyl/aryl-2-oxazoline)-polyethylenimine (POZ-PEI) copolymers resulting from the partial hydrolysis of poly(2-alkyl/aryl-2-oxazoline)s (POZs) offer highly tunable properties. The amine groups on the PEI units are suitable for a range of postpolymerization modifications such as ring-opening of epoxides, acylation, and coupling. The reactivity of these amines can be controlled by altering the available structural variables of the copolymer. This makes these copolymers promising candidates as thermal latent curing agents (TLCs) for cross-linking of epoxides. In this paper, a range of POZ homopolymers with different alkyl/aryl pendant groups (ethyl/propyl/pentyl/phenyl) and molar masses (1000, 2000, and 5000 g/mol) were hydrolyzed at different hydrolysis ratios (25%, 50%, and 75%) to sy
