聚乳酸用熔体强度增强剂的合成及表征

Synthesis And Characterization Of Melt-strength enhancer For Poly lactic acid

以丙烯酸酯为单体,采用乳液聚合体系,合成聚乳酸用熔体强度增强剂。通过电镜(SEM)、红外分析(IR)、高效凝胶色谱、转矩流变仪等手段对其结构及性能进行了表征。结果表明:本文合成的丙烯酸酯类熔体强度增强剂从结构及性能,都与PARALOIDBPMS-265相似。

<Abstracts>Using acrylate as monomer, polymerization system by emulsion, synthesis of melt-strength enhancer. for polylactic acid . Its structure and properties were characterized by electron microscopy (SEM),infrared spectroscopy (IR), high performance gel chromatography, torque rheometer etc.The results show that: synthetic acrylic melt-strength enhancerof this paper from the structure and the performance was similar to that of PARALOID BPMS-265.
