摘要：
Cellulose graft poly(butyl methacrylate) copolymers (Cellulose-g-PBMA) were prepared by homogeneous atom transfer radical polymerization (ATRP) process. Cellulose chloroacetate(Cellulose-ClAc), as macroinitiator, was synthesized first by direct acylation of cotton pulp cellulose with chloroacetyl chloride (ClC2OCl) in cellulose/LiCl/DMAc solution. Thereafter, Cellulose-ClAc was used for the ATRP of BMA (butyl methacrylate) mediated by the FeCl2/four-dimethyl aminopyridine (DMAP) catalytic system. Acylation reaction and grafting polymerization conditions, such as reaction time, reaction temperature and ratio of reactants were investigated. The hydrophobicity of Cellulose-g-PBMA copolymer was studied with contact angle measurements. Cellulose-ClAc and Cellulose-g-PBMA were characterized by means of FTIR, NMR, SEM, TEM, AFM. Gel permeation chromatography (GPC) was used to analyze the characteristics of the activity of polymerization. © All Rights Reserved.
