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。

【Mater Sci Eng C】Preparation of poly(cyclooctene)-g-poly(ethylene glycol) (PCOE-g-PEG) graft copolymers with tunable PEG side chains via ROMP and its protein adsorption and platelet adhesion properties
In our previous work [H. Shi, D. Shi et al., Polymer Chemistry 2(2011)679–684], polycyclooctene-g-PEG (PCOE-g-PEG) copolymers were synthesized via ring opening metathesis polymerization (ROMP) from PEG functionalized cyclic olefin macromonomers and cyclooctene. The grafting degree and the grafting site were easily controlled through the “grafting through” approach. The PCOE-g-PEG film surface w...

Functional Poly(ε-caprolactone)s via Copolymerization of ε?Caprolactone and Pyridyl Disulfide-Containing Cyclic Carbonate: Controlled Synthesis and Facile Access to Reduction-Sensitive Biodegradable Graft Copolymer Micelles
Pyridyl disulfide-functionalized cyclic carbonate (PDSC) monomer was obtained in four straightforward steps from 3-methyl-3-oxetanemethanol and exploited for facile preparation of functional poly(ε-caprolactone) (PCL) containing pendant pyridyl disulfide (PDS) groups via ring-opening copolymerization with ε-caprolactone. The results showed that PDS-functionalized PCL polymers were ...

Graft Copolymerization of Styrene and Acrylonitrile in the Presence of Polypropylene Glycol: Modeling and Simulation of Semi-batch and Continuous Processes.
关键字：接枝聚合，动力学，半连续过程，连续过程
An existing kinetic model for graft free-radical copolymerization of styrene (St) and acrylonitrile (AN) in the presence of poly(propylene glycol) is extended to describe the semi-batch process and to simulate the continuous process. A good predictive ability of the model for the semi-batch process is demonstrated by comparing with experimental data, except for Mw and polydis...
