Controlled Synthesis of Sustainable Block Copolymer Compatibilizers

Aliphatic polyesters are an attractive class of sustainable materials, as polymers such as poly(lactic acid) can be derived from biomass and are biodegradable. However, the range of applications of aliphatic polyesters is currently limited by their material properties. The formation of polymer blends (combining two different types of polymer) is an attractive method of adapting the material properties and thus expanding the range of applications. However, the different polymer components can phase separate leading to poorer properties; this can be overcome by using a compatibilizer. This project will focus on developing block copolymers as compatibilizers to form polymer blends with a range of properties.
