【摘要】 以聚己二酸丁二醇酯(PBA,1000),4,4′-二苯基甲烷二异氰酸酯(MDI)和1,4-丁二醇为原料考察了水分对热塑性聚氨酯(TPU)连续聚合工艺的影响,研究了水分含量对硬度、软化点及熔融指数的关系,并采用红外的方法研究了水分含量对TPU结构的差别。更多还原

【Abstract】 A thermoplastic polyurethane elastomer based on PBA 1000 as soft segments,isophorone diisocyanate and 1,4-butanediol as hard segments was syntheized for the reseach on water as a reactant by Twin-screw Extruder.The hardness、softening point and melt index were studied by the addition of water,and the difference of the TPU structure was considerred by FTIR.更多还原
