Autor: Yang Ji-yuan, Gu Zhong-wei, Feng Xinde, Chen Xian-li, Ye Wei-ping, Zhong Ge-wen, Li You-xin

Publikováno v: Journal of Controlled Release. 22:3-14

Three types of triblock copolymers, ABA, ABC and ACB, where A, B and C are poly (ϵ-caprolactone) (PCL), pply- dl -lactide (PLA) and polyglycolide (PGA), respectively, were synthesized by living polymerization of the purified monomers, ϵ-caprolacton

The radiation grafting of N-vinyl-2-pyrrolidone to segmented polyetherurethane in alkaline meduim

Autor: Pan Yingdong, Ha Hongfei, Feng Xinde, Yang Fuliang, Wu Jilan

Publikováno v: Radiation Physics and Chemistry (1977). 25:501-508

The gamma radiation grafting of N-vinyl-2-pyrrolidone (N-VP) to segmented polyetherurethane (SPEU) was studied. The grafting was performed by the preswelling technique. In this work the experiments of the polymer films preswollen in N-VP-aqueous solu

Transformation of cationic polymerization of tetrahydrofuran into anionic block copolymerization of methyl methacrylate

Autor: Tseng Shen-Son, Zhang Hongzhi, Feng Xinde

Publikováno v: Polymer Bulletin. 8:219-224

A new approach has been developed to transform the cationic polymerization of tetrahydrofuran (THF) into anionic block copolymerization of methyl methacrylate (MMA). Several telechelic polytetrahydrofurans with secondary amine end-groups (PTHF-NHR, w
