Study on Compatibilized Polyethersulfone and Polycarbonate Blends
(1890-1904) Journal of Macromolecular Science, Part B - Physics 50  #10 (2011)
Zhang et al of JiLin University, China, used a multiblock copolymer of polyethersulfone (PES) and polycarbonate (PC) as a compatibilizer for a blend of PES/PC.  The addition of the compatibizer improved the compatibility between PES and PC. It was found that the interfacial adhesion was enhanced; the size of the dispersed phase was reduced and this resulted in an improvement of elongation at break and tenacity of PES/PC blends and tensile strength and tensile modulus were almost constant.  (RDC 8/22/2011)
