摘要

采用异山梨醇型聚碳酸酯（DB），与掺混型ABS熔融共混制备了具有不同聚丁二烯（PB）含量和丙烯腈（AN）含量的DB/掺混型ABS合金，并在考察掺混型ABS特征对合金结构与性能的影响的基础上，分别使用同种掺混型ABS以及各种商品化ABS树脂，比较了DB/ABS合金和双酚A型聚碳酸酯/ABS合金的性能及其变化规律.结果表明，对DB/掺混型ABS（70/30）合金而言，PB含量变化对于合金拉伸性能的影响明显大于AN含量变化所带来的影响，在PB含量为6.3 wt%条件下，各不同AN含量的合金体系均有最好的性能表现.PB含量和AN含量变化对合金分散相形态的影响与力学拉伸性能变化特征一致.DB/ABS合金体系均具有良好的热稳定性与热力学相容性，受AN含量和PB含量变化的影响较小，合金玻璃化转变温度与DB非常接近.以双酚A型聚碳酸酯为基础的聚碳酸酯（PC）/ABS合金及以异山梨醇型聚碳酸酯为基础的DB/ABS合金，在拉伸性能变化上均表现出完全相同的规律，且无论是采用掺混型ABS还是采用商品化ABS的体系，PC/ABS与DB/ABS合金在拉伸性能所反映出的规律也是基本一致的.

Abstract

Blending type of ABS with different polybutadiene rubber (PB) and polyacrylonitrile (AN) contents in SAN phase is prepared at 240℃ to study the effects of PB and AN content on the structure and the properties of DB/ABS blends. Different kinds of productive ABS along with the blend-type ABS are used to compare the properties of PC/ABS and DB/ABS blends comprehensively. All blends are made by melt blending for 10 min with sheer rate of 30 r/min. The result shows that

in DB/Blend-type ABS (70/30) blends

PB content exhibits significant influence on the tensile properties. Samples with 6.3 wt% of PB always show the best performance both in yield strength and elongation at break when AN content is fixed at 18 wt%

25 wt% and 30 wt%; while increasing AN content in the sample with the same PB content would result in better blends properties even not so obvious as PB content. Scanning electron microscopy gives exactly the same trend for phase morphology with PB and AN contents

revealing best uniform scale of dispersed phase (ABS) among 0.5-1.2 μm at 6.3 wt% of PB. Thermal gravimetric analysis shows that all DB/ABS blends have good thermal stability

which is not obviously affected by PB content and AN content. Single peak of glass transition shows good compatibility in the DB/ABS blends. Excellent compatibility of DB with ABS in the sample is exhibited through dynamic mechanical analysis. The glasstransition temperature of DB/ABS blends are closed to that of DB

mildly affected by PB and AN content. Besides

both blending type ABS and different kinds of productive type ABS are used to compare the properties of DB/ABS blends and traditional bisphenol-A-type PC/ABS blends. Basic laws of tensile properties in DB/ABS remain the same as in PC/ABS blends using different types of ABS.
