Monomer reactivity ratio and thermal performance of α-methyl styrene and glycidyl methacrylate copolymers

Investigation of microstructure of glycidyl methacrylate/a-methyl styrene copolymers by 1D- and 2D-NMR spectroscopy

The copolymers of glycidyl methacrylate/a-methyl styrene were synthesized. The quantitative C{H}-NMR spectroscopy was used to determine the copolymer compositions. The distortionless enhancement by polarization transfer, C-H heteronuclear single quantum coherence and total correlation spectroscopy were used for the complete spectral assignment of C{H}and H-NMR spectra.

Copolymers of 2,5-bis[(4-methoxyphenyl) oxycarbonyl]styrene with styrene and methyl methacrylate: Synthesis, monomer reactivity ratios, thermal properties, and liquid crystalline behavior

Copolymers of a liquid crystalline monomer, 2,5-bis[(4-methoxyphenyl)oxycarbonyl]styrene (MPCS), with St and MMA were prepared by free radical polymerization at low conversion in chlorobenzene with 2,20-azobisisobutyronitrile (AIBN) as initiator. The copolymers of poly(MPCS-co-St) and poly(MPCS-co-MMA) were characterized by H NMR and GPC. The monomer reactivity ratios were determined by using t...

effects of maleic anhydride and glycidyl methacrylate on morphological and physical properties of styrene wood-polymer

the current research was planned to investigate the effect of maleic anhydride (man) and glycidyl methacrylate (gma) treatments on morphological and physical properties of the hornbeam wood-styrene composite. test samples were divided according to astm d4446-05 to control and treated with man, st, man/st and man /st/gma. treatment was performed by vacuum- pressure method using a experimental cy...

Computational study of cyclohexanone-monomer co-initiation mechanism in thermal homo-polymerization of methyl acrylate and methyl methacrylate.

This paper presents a systematic computational study of the mechanism of cyclohexanone-monomer co-initiation in high-temperature homopolymerization of methyl acrylate (MA) and methyl methacrylate (MMA). Previous experimental studies of spontaneous thermal homopolymerization of MA and MMA showed higher monomer conversion in the presence of cyclohexanone than xylene. However, these studies did no...
