Abstract

Summary: Polyanhydrides were synthesized from aliphatic and aromatic diacids using microwave radiation without vacuum at significantly reduced reaction times when compared to conventional melt polycondensation. Reaction conditions, such as duration of polymerization, equivalents of acetic anhydride, and choice of starting species, were studied. In addition, copolymers were synthesized and monomer sequence lengths were calculated using dyad conditional probabilities. The results are in good agreement with monomer sequence lengths from conventional copolymerization.

Comparison of the monomer sequence lengths in poly(CPHโ€coโ€SA) synthesized both conventionally and by microwave heating.

## Abstract Soybean oil is one of the most promising renewable raw materials for polymers. Cationic copolymerization with a variety of olefinic monomers gives interesting materials but the curing process is tedious and high temperatures and long reaction times are needed. We studied the cationic ho
