| Abstract |
Copolymerization of MAn and CHDDVE was conducted by using azobisisobutyronitrile
(AIBN) or benzoyl peroxide (BPO) as the initiator, ethyl acetate (EA) or n-butyl acetate (BA) as the
solvent, and n-hexane as the precipitator. Effects of several factors on monomer conversion were
studied, such as reaction time, reaction temperature, composition of the monomer feed
(MAn/CHDDVE) and initiator concentration. Molecular weight and its polydispersity and polymer
material morphology were characterized by gel permeation chromatography (GPC) and transmission
electron microscope (TEM) technologies, respectively. It was demonstrated that CTC was formed in
MAn/CHDDVE system, based on ultraviolet-visible spectroscopy (UV-vis) analysis. The product
was alternating copolymer with high crosslinking degree, so it could not be dissolved in common
solvents, e.g. water, chloroform, N, N-dimethyl formamide (DMF), tetrahydrofuran (THF) and
acetone (Ac). |
