Evaluation and characterization of vector fluids and peroxides in a process of in situ compatibilization of polyethylene and polystyrene

摘要

An organic functional silane was found to be the most efficient among several vector fluids in reactive blend compati- bilization of the polyethylene (PE)/polystyrene (PS)/ peroxide/vector fluid system. This paper involves further analysis of this reactive blending system. Surface tension data was used to calculate spreading coefficients which were compared to the amount of PE-PS copolymer formed during blending. A good correlation between a computed spreading coefficient and the degree of grafting of PS onto PE was found.
