Copolymerization of 4-methyl- and 4-methoxyphenyl acrylates with glycidyl methacrylate: Synthesis, characterization, reactivity ratios, and application as adhesives for the leather industry

摘要: Copolymers of 4-methyl- and 4-methoxyphenyl acrylates with glycidyl methacrylate having different copolymer compositions were synthesized in 1,4-dioxan using benzoyl peroxide as a radical initiator at 70 ± 0.5°C. The composition the monomers copolymers calculated 1H-NMR spectroscopy by comparing integral values well-separated aromatic alifatic proton peaks. reactivity ratios Fineman-Ross, Kelen-Tudos, extended Kelen-Tudos methods. characterized decoupled 13C-NMR spectroscopic techniques. Gel permeation chromatography was used for determining polydispersity indexes copolymers. Thermal stability homo- thermogravimetric analysis, while differential scanning calorimetry utilized glass transition temperature. suitable chosen curing reactions diethanolamine chloroform. cured resins tested adhesives leather-leather bonding temperatures (50, 90, 100, 110°C). It found that copoly(MOPA-GMA) 50°C gave best adhesive property over all other samples tested. © 1996 John Wiley & Sons, Inc.
