环氧类扩链剂ADR-4468改性氯化聚丙撑碳酸酯/聚丁二酸丁二醇酯共混物的制备及其性能
Preparation and Properties of Chlorinated Poly(Propylene Carbonate)/Poly(Butylene Succinate)Blends Modified with Epoxy Chain Extender ADR-4468
摘要
Abstract
Chlorinated poly(propylene carbonate)/poly(butylene succinate)(CPPC/PBS)blends were modified with ADR-4468,and a series of CPPC/PBS/ADR blends were prepared by melt blending method.The effects of the mass percentage of ADR-4468(0%～3.5%)on the structure,thermal properties,compatibility,rheological properties,mechanical properties and adhesive properties of the CPPC/PBS/ADR blends were investigated.The results of Fourier transform infrared spectroscopy(FT-IR)and gel permeation chromatography(GPC)showed that the epoxy groups of ADR-4468 can react with the end groups of the two polymers to form chain extension products.The results of dynamic mechanical properties showed that the reactive compatibilization improved the compatibility between CPPC and PBS.Thermal properties showed that the glass transition temperature(Tg,CPPC)and thermal decomposition temperature(Td5%)of the blends with incorporation of 3.5%ADR were increased by 8.1 and 28.7℃,respectively,compared with those of the CPPC/PBS blends.The results of rheological properties showed that the incorporation of ADR-4468 can effectively improve the storage modulus(G'),loss modulus(G″)and complex viscosity(|η*|)of the CPPC/PBS/ADR blends.When the mass percentage of ADR-4468 was 3.5%,the tensile strength and Young's modulus of CPPC/PBS/ADR blends were 37.7 and 723.5 MPa,respectively,which were 123%and 68%higher than those of CPPC/PBS blends.The lap shear strength of CPPC/PBS/ADR blends on stainless steel increased first and then decreased,with a maximum value of 4.83 MPa,which was 53%higher than that of CPPC/PBS blends.In addition,the CPPC/PBS/ADR(80/20/1.5)blend has good adaptability on different substrates.Therefore,the CPPC/PBS/ADR blends have good thermal stability,mechanical properties and adhesive properties,and have potential applications in the field of environmentally friendly hot melt adhesives.关键词
