| 7. | In addition , the preparation of aqueous starch microgel with aqueous solution as reaction environment has been studied . the results show that the important factors affecting the formation of starch microgel are surfactant content , concentration of starch and conversion efficiency of cross - linking reaction
另外，本论文研究了用水溶液作为反应环境制备亲水性淀粉微凝胶，研究得到表面活性剂含量、淀粉液浓度及交联反应的转化率是影响淀粉微凝胶形成的主要因素。 |
| 8. | Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized . when the polymer is dispersed in water , the silane alkoxy end - groups of the polymer undergo hydrolysis , followed by condensation to form a stable cross - linked aqueous dispersion . tem studies indicated that with more incorporation of hydrophilic sites , the particle size of the dispersion decreased . it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher . the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc . it was also found that the cross - linking density of the casting film may increase during the film formation and drying process
将硅氧烷封端的含亲水基团的线性聚氨酯预聚体分散于水中，获得稳定的聚氨酯分散体.由于硅氧基团水解、缩合，在分散体粒子内产生扩链交联反应，生成了交联水基聚氨酯分散体.透射电子显微镜研究表明分散体粒径小、分布宽.扫描电子显微镜研究了成膜结构及成膜性能与粒径的关系.溶胀实验计算获得的两交联点之间的平均分子量与理论平均分子量相符.研究还发现此分散体膜在干燥过程中可进一步交联.膜的水溶胀及机械性能表明，此分散体具有极大的工业应用价值 |
| 9. | Preparation , structure and properties of hdpe ~ g ~ aa / mmt nanocomposites melt grafting reaction of hdpe with aa was performed in thermohaake rheomix and hdpe - g - aa with high grafting degree and high grafting efficiency was prepared . the change of torque indicated that the graft copolymerization was existed during melt compounding . the extent of grafting was analyzed by ftir and element analysis
在hdpe中只加过氧化二异丙苯( dcp )时，由于发生交联反应而使平衡扭矩明显增加，熔点和结晶度降低，加入aa后， aa与hdpe的接枝和hdpe自身的交联并存，前者对后者有抑制作用，从而使扭矩下降，熔点和结晶度部分恢复。 |
