Abstract:

The compatibilization of immiscible poly(n-butyl methacrylate)(PBMA)/polystyrene(PS) blends was realized by the reaction of furan and maleimide groups. The furan-functionalized poly(n-butyl methacrylate)(P(BMA-co-FMA)) and maleimide-functionalized polystyrene(MPS) was synthesized by copolymerization and post-polymerization modification, respectively. The Diels-Alder reaction of the functionalized polymers and their blend were confirmed by nuclear magnetic resonance spectroscopy(NMR). The reaction of furan and maleimide dramatically promoted the compatibility of two components, confirmed by a homogeneous microstructure evidenced by transmission electron microscopy(TEM) observation and by the presence of a single glass transition temperature in the (P(BMA-co-FMA)/MPS blends. The properties of the blend materials could be controlled conveniently by adjusting the reaction time, and the blends transformed from tough material to brittle material gradually as the reaction processed, which was confirmed by the three point bending test.
