CacO3在PP和PP/mPE共混物基体中的作用比较

研究CaCO3填料在取丙烯（PP）和茂金属聚乙烯（mPE)弹性体增韧PP共混物（PP／mPE)2种基体中的不同作用。结果表明：在PP基体中，填料显著提高其刚性，而在共混物基体中，由于弹性体的存在，填料的增强作用减弱；弹性体能够改善填料粒子和基体的界面粘合，增大弹性体分散相的尺寸，使PP/mPE共混物的拉伸断裂韧性提高。低温下（－30℃）的Charpy缺口冲击实验表明：少量的CaCO3即可导致PP/mPE体系冲击强度的迅速下降。

Structure–property relationships of poly(urethane urea)s with ultra‐low monol content poly(propylene glycol) soft segments. I. Influence of soft segment molecular weight and hard segment content

Structure–property relationships in poly(urethane urea)s synthesized with ultra‐low monol content poly(propylene glycol) soft segments were investigated as soft segment molecular weight (2000, 4000, and 8000 g/mol) and hard segment content (6.3 and 9.0 wt %) were varied. Morphological features such as interdomain spacing and interphase thickness were quantified and revealed with small‐angle X‐ray scattering (SAXS) and atomic force microscopy (AFM). The thermal and mechanical behavior was assessed with a dynamic mechanical analyzer (DMA) and by differential scanning calorimetry (DSC) and stress‐strain tests. Hard segment content, over the limited range studied, had little effect on the morphology and soft segment thermal and mechanical properties. The molecular weight of the soft segments had considerably more influence on the morphology and mechanical properties. Increasing soft segment molecular weight resulted in greater interdomain spacings, as shown by SAXS, and a noticeable change in the structure, as shown by AFM. Additionally, as soft segment molecular weight decreased the soft segment glass transition broadened and rose to higher temperatures. © 2002 Wiley Periodicals, Inc.

CaSO4晶须/聚氨酯弹性体复合材料性能的研究

笔者主要研究了CaSO4晶须对聚氨酯弹性体复合材料热性能和摩擦性能的影响。随Ca-SO4晶须含量的增加，复合材料的起始分解温度被提高，加入CaSO4晶须并未改变聚氨酯弹性体的化学结构，只是减慢了聚氨酯弹性体的热失重速率；随着CaSO4晶须含量的增加，聚氨酯弹性体复合材料的磨耗量降低。分析认为，加入CaSO4晶须后。阻止了聚氨酯弹性体结构的大面积破坏，改变了磨屑的形成机理，使其由纯聚氨酯的大的片状磨屑变为复合材料的小磨屑，从而降低了聚氨酯复合材料的磨损。     

Synthesis and elastomer behavior of a novel polymer electrolyte of acrylic ester–salt copolymer

This paper studied the synthesis of a novel elastomeric copolymer electrolyte in an aqueous phase. The monomer, sodium allyl sulfonate (SAS), was dissolved in continuous aqueous phase and the second monomer, methyl acrylate (MA), was supplied from MA micelles as dispersed phase. The copolymerization of the two monomers took place in continuous aqueous phase. Confirmed by FTIR and ¹H‐NMR, a binary copolymer electrolyte of MA and SAS, poly(MA‐co‐SAS), was obtained. The glass transition temperature of the copolymer was indicated as 20.4°C by DSC thermogram, thus, it behaves an elastomer in normal ambient temperature. The mechanical properties of the composite films consisting of both poly(MA‐co‐SAS) and Cu²⁺ ions or reduced copper were affected by the content of ions and reduced copper. © 2006 Wiley Periodicals, Inc.
