As the pre-assembly of AA monomers onto the PAAC template, copolymers from the template system exhibited significantly longer AA and AM sequences compared with those of copolymers from non-template system s. 由于共聚合体系中AA单体在PAAC模板聚合物上预组装,使得模板体系共聚物比无模板体系共聚物的AA和AM序列长度显著增加。
Synthesis of PAAc hydrogel by microwave irradiation and its swelling behavior 微波辐照合成聚丙烯酸水凝胶及其性能研究
Swelling and Drug Releasing Properties of P ( NIPAAm-co-AAm) Hydrogels and PAAc/ P ( NIPAAm-co-AAm) IPN Hydrogels P(NIPAAm-co-AAm)共聚凝胶和PAAc/P(NIPAAm-co-AAm)IPN凝胶的溶胀与释药性能
The surface composition and microstructure of the modified films were characterized by XPS and ATR-FTIR. It was shown that PAAc formed on the surface and the PTFE-g-PAAc films were obtained ultimately. 通过XPS和ATR-FTIR对改性膜的表面进行表征,表明在PTFE膜的表面形成一层聚丙烯酸(PAAc)薄膜。
The rate of polymerization was found to be proportional to the concentration of monomers and initiator with exponents of 1.1 and 0.83, respectively, which are larger than the ordinary values due to the effect of PAAC. 同时发现聚合反应速度分别和单体浓度及引发剂浓度的11和083次方成正比,由于模板的作用数值高于常规值。
Confined within our experiment, PAAC reduces the membrane fluidity under the high temperature stress, more importantly, it can stabilize the fluidity of membrance, however, it has no effect on the change of the transition temperature. 在实验范围内,高温胁迫下同样降低膜的流动性,最重要的是能够稳定膜的流动性,但对相变温度的改变似乎不起作用。
