摘　　要：通过两步法制备可逆感温变色聚丙烯(PP)专用料,首先将乙烯-辛烯共聚物(POE)与可逆感温变色粉于微型双螺杆挤出机中挤出造粒制备色母料,然后将PP与色母料熔融共混挤出制备可逆感温变色PP专用料。探讨了色母料含量对PP专用料感温变色性能、力学性能、热学性能及微观形貌的影响。结果表明,利用POE与PP良好的相容性,实现了可逆感温变色粉在PP基体中均匀的分散,可逆感温变色PP专用料表现出优异的可逆感温变色性能和冲击性能。The reversible thermochromic polypropylene(PP)special materials were prepared by a two-step method.A master batch based on poly(ethylene-1-octene)(POE)and reversible thermochromic powder was first prepared by a miniature twin-screw extruder.The reversible thermochromic PP special materials were then prepared by melt blending PP with the resulting master batch.The effect of master batch content on the reversible thermochromic property,mechanical properties,thermal properties and microstructure of the prepared special materials were investigated.The results indicated that the reversible thermochromic powders were finely dispersed in the PP matrix because of the good compatibility between POE and PP matrix.The PP special materials exhibited an excellent reversible thermochromic property and high notched impact strength.
