织物后整理用氨基硅油的合成研究

研究了本体阴离子聚合合成织物后整理用氨基硅油 ,考察了温度、催化剂浓度、原料单体配比等对聚合过程及产物性能的影响。就氨基硅油产品的氨值指标而言 ,在聚合达到平衡时 ,原料中氨基单体的含量是其主要影响因素 ;对黏度而言 ,则受3种因素共同影响 ,并且与 3种因素近似呈正比关系。而要大幅度提高聚合产物黏度 。

多尺度作用的D_4/APAEDMS本体共聚过程仿真

For high viscosity bulk-copolymerization of octamethylcyclotetrasiloxane and amino-silicone monomer, a multisyphon flow physical model was established.Based on the free volume and chemical reaction kinetic theories, a new computational model was developed to simulate the multisyphon flow model. As to the new model, the united influence of reaction and diffusion was reviewed and analyzed. The new model was used to simulate bulk- copolymerization of octamethylcyclotetrasiloxane and amino-silicone monomer and agreed well with the results.
