摘要
以植物油基环氧油酸甲酯(EMO)为原料,合成功能性高分子单体丙烯酸油酸甲酯(AMO)。通过红外光谱和核磁共振图谱研究表明,AMO分子中具有明显的丙烯酸基的特征吸收峰。通过差示扫描量热仪测试分析,AMO的玻璃化转变温度(Tg)为-82℃。研究了不同反应时间和催化剂对反应的影响,表明N,N二甲基甲苄胺比三苯基膦更适合EMO催化加成AMO。将AMO和甲基丙烯酸甲酯单体聚合,可以制备出低粘、可剥离压敏胶。
A novel monomer acrylate methyl oleate（AMO）capable of forming high molecular weight polymers was synthesize from a plant oil-based epoxidized methyl oleate（EMO）. The Analyses and characterization of AMO were carried out with FTIR and ^1H-NMR spectrum exhibited that the acrylic acid group was in AMO. The DSC showed that the glasstransition temperature （Tg） of AMO was --82℃. The influences of the initiators reaction time were investigated that N,N- dimethyl benzyol amine was a suitable catalyst than triphenyl phosphine synthesized AMO. It was found that the pressure sensitive adhesive made from copolymer of AMO and methacrylate methyl ester could be low tack and strippable performance.
