Facile synthesis of dual-responsive thioether-bridging graft copolymers by combination of controlled polymerization and thio-bromo click reaction
关键字：stimuli-responsive，click reaction，ring-opening polymerization
Synthesis of stimuli-responsive exact graft polymers with multisegmented backbone and well-controlled grafting
density can provide us with insights into structure-property correlations as well as multipurpose applications in
smart materials. Given the great potential of stimuli-labile linkages in materials science, this study describes
synthesis of thermo/oxidation-responsive poly(N-iso...

Graft Copolymerization of Styrene and Acrylonitrile in the Presence of Poly(propylene glycol): Kinetics and Modeling.
关键字：接枝聚合物，苯乙烯，丙烯腈，聚醚，动力学，模型
A heterogeneous polymerization model, including an initial solution polymerization model and a later two-phase polymerization model, is developed to describe graft free-radical copolymerization of styrene and acrylonitrile in the presence of poly(propylene glycol). The diffusion-controlled termination, initiation, propagation, and transfer in the dispersed phase are cons...

关键字：antibacterial, UV-induced graft polymerization, polypropylene nonwoven fabric membrane, hemocompatibility, zwitterionic polymer
In this article, a facile approach to fabricate a biofunctional polypropylene nonwoven fabric membrane (PP NWF) with a switchable surface from antibacterial property to hemocompatibility is presented. In the first step, a cationic carboxybetaine ester monomer, [(2-(methacryboxy) ethyl)]-N,N-dimethylamino-ethylammonium bromide, methyl ester (CABA-1-ester) was synthesized....

Improved biocompatibility and antifouling property of polypropylene non-woven fabric membrane by surface grafting zwitterionic polymer
关键字：Antifouling, Graft polymerization, Polypropylene non-woven fabric membrane, UV-irradiated, Zwitterionic polymer
This work described the graft polymerization of a zwitterionic polymer, [3-(methacryloylamino)propyl]-dimethyl(3-sulfopropyl) ammonium hydroxide (MPDSAH), onto polypropylene non-woven fabric (NWF) membrane via O2 plasma pretreatment and UV-irradiated technique. The surfaces of the modified NWF membranes were principally characterized using attenuated total reflectance Fourier transform i...

PEG-PCL 基温敏性嵌段-接枝共聚物胶束化与凝胶化
关键字：Block-graft copolymers，Micellization，Sol-to-gel transition
A series of triblock-graft copolymers PEG-b-[PCL-g-P(MEO2MA-co-OEGMA)]-b-PEG were synthesized by combination of ring-opening polymerization (ROP) and atomic transfer radical polymerization (ATRP). The phase transitions induced by temperature have been studied. The synthesized triblock-graft compolymer not only exhibited a hydrophilic, but also have temperature sensitivity. The triblock-graft c...

嵌段和接枝反应型相容剂的相容特性
关键字：Polymer blends, Situ compatibilization, Graft copolymer, Block copolymer
绝大多数聚合物都是不相容的，直接混合很难提高它们的机械性能，因此在聚合物共混过程中需要直接加入相容剂或原位生成相容剂（原位相容）以提高产物的综合性能。

接枝相容剂结构对PS/PA6 共混体系相容特性影响
关键字：Polymer blends, Emulsification efficiency, Graft copolymer, Molecular architecture
聚合物共混能使两种或两种以上的聚合物混合在一起，得到综合性能优于任何单一组分的高分子材料。但是大多数聚合物是不相容的，直接混合很难提高它们的机械性能。
