Block copolymerMMAHEAAmPMMA-b-PHEAAmAtom transfer radical polymerizationDiblock copolymers consisting of methylmethacrylate (MMA) and N-hydroxyethylacrylamide (HEAAm) polymer were successfully synthesized via direct two steps atom transfer radical polymerization (ATRP). At first, poly(methylmethacrylate) (...
1) poly-β-hydroxyethyl methacrylate 聚甲基丙烯酸-β-羟乙酯1. Then K_2S_2O_8 as initiator,the silica sol reacted withβ-hydroxyethyl methacrylate(HEMA),the gel of SiO_2/poly-β-hydroxyethyl methacrylate(PHEMA) synthesized. 采用溶胶-凝胶法,以正硅酸乙酯为无机先驱体、盐酸为催化剂合成二氧化硅(...
Microparticles of crosslinked poly(2-hydroxyethyl methacrylate) were prepared by suspension polymerization. Their crosslinked structure was determined by equilibrium and dynamic swelling experiments in water. The number-average molecular weight between crosslinks, Mc, was a function of the crosslinking ratio...
The molecular mobility of poly(2-hydroxyethyl acrylate) (PHEA) and of its copolymers with 2-hydroxyethyl methacrylate (H EM A) was determined by means of dynamic mechanical measurements with a torsional pendulum. The low-temperature dispersion assigned to the motion of the hydroxyethyl groups of ...
In this work, a novel graft copolymer, hydroxyethylcellulose-graft-poly(2-(dimethylamino)ethyl methacrylate) (HEC-g-PDMAEMA), used as physical coatings of the bare fused-silica capillaries, was synthesized by using ceric ammonium nitrate initiator in aqueous nitric acid solution. EOF measurement resu...

1. A lipstick composition consisting of (a)polyHema fibers or copolymer of polyHema fibers wherein the monomer is selected from the group consisting of acrylic acid, methacrylic acid, crotonic acid, hydroxyethylmethacrylate, hydroxyethylacrylate, hydroxypropylacrylate, hydroxypropyl methacrylate, hydroxybuty...
Poly(2-hydroxyethyl methacrylate) (hereinafter referred to as polyHEMA in some case) has been evaluated as a polymer which is relatively excellent in biological affinity or biocompatibility, and ABA type block copolymer containing HEMA segment in the molecule is further proposed for a biocompatible me...
