| 摘 要： | 探讨了经过特殊表征的有机刚性粒子—ＰＭＭＡ基核－壳型有机刚性粒子（ｃｏｒｅ－ｓｈｅｌｒｉｇｉｄｏｒｇａｎｉｃｆｉｌｅｒ）对Ｒ－ＰＶＣ／ＣＰＥ体系的增韧和增强作用及其对加工流变性的影响。研究发现，适当粒径的核－壳型粒子与Ｒ－ＰＶＣ／ＣＰＥ基体在适当配比下共混，常温（２３℃）下，可使ＰＶＣ／ＣＰＥ基体的冲击强度和断裂伸长率得到提高，断裂强度、屈服强度、硬度和加工流变性也有所改善，而在低温（－１０℃）下几乎没有增韧效果。

| Abstract: | The toughness and reinforcement of R PNC/CPE and the influence of its processing rheological property by modification with PMMA basic core shell rigid organic filler particularly characterized were investigated. It was found that the impact strength and the elongation at break of PVC/CPE by blending with proper diameter PMMA basic core shell rigid organic filler at right ratio were raised, and that the tensile strength at break, the yield strength, the rigidity and processing rheological property of matrix were also improved to a certain extent under normal temperature(23℃) but at low temperature (-10℃) PVC/CPE was hardly toughened by this filler . |
