Synthesis and characterization of polycarbonate/polydimethylsiloxane multiblock copolymer prepared from dimethylsiloxane and various aromatic dihydroxyl monomers
This study utilizes different types of bisphenol monomers instead of bisphenol-A to synthesize phenol terminated polydimethylsiloxane-polycarbonate block copolymers. The copolymers were synthesized by interfacial phosgenation of alpha, omega-phenol-organofunctional polydimethylsiloxane oligomer with various aromatic dihydroxyl monomers. In addition,the thermal properties, flammability, and mechanical properties of the synthesized copolymers after extrusion and injection molding were investigated.
