增塑作用

Alkylphenols are applied widely as the rubber additives surfactants in domestic and industrial products, antioxidants and so on. As it's decomposer, nonylphenol has a steady chemical characteristics and exist widely in environment. As it's molecule structures are similar as 17beta-estradiol in human body, and it can combine with estradiol receptor simulating it, disrupt endocrine system and induce health damage effect. Many studies on environmental endocrine disrupting chemicals approved that NP have weaken estradiol functions.

烷基酚被广泛用作塑料增塑剂、农药乳化剂、纺织行业的整理剂等，作为其降解产物壬基酚(nonylphenol，NP)的化学性质稳定，环境分布广泛，由于其分子结构与人体内雌二醇的分子结构相似，许多环境内分泌干扰的实验研究结果证实壬基酚具有雌激素样作用，可以模拟雌激素与体内雌激素受体结合，干扰机体的内分泌代谢，导致健康危害效应。

The influence of the glycerol contents on the plasticizing and mechanical properties were studied.

疏水性单体的引入使材料的力学强度提高，对凝胶体系具有增塑作用的是非冻结水而不是可冻结的结合水和自由水。

The feasibility of the equipment to measure Tg of amorphous powder is verified with a lot of experimentl results.The Tgs of some typical starches such as corn, pachyrhizus, buckwheat and pea in different water content are obtained by TDA. It is found that the water has plastic effect on starch and the Tg of starch decreases with the increase of water content. Through this study a quantitative expression is established to relate Tg and water content, and it is testified with experimental results for the sticky rice starch with different water content.
