摘要

合成了一种末端叔丁基的甲基丙烯酸氨基乙酯（2-（叔丁基氨基甲酰基）氧基）甲基丙烯酸乙酯（tBEM），并将其掺入一系列均相核壳型丙烯酸酯乳液中。与具有线性或环烷基末端基团的氨基丙烯酸酯不同，叔丁基似乎阻止了氨基丙烯酸酯的形成，而不是采用异氰酸叔丁基与甲基丙烯酸2-羟乙基（HEMA）直接反应的方法。采用最小成膜温度（MFFT）测试仪、差示扫描量热法（DSC）、动态力学分析（DMA）、拉伸试验和傅里叶变换红外光谱（FTIR）等方法研究了tBEM含量对乳胶性能的影响。随着加载水平的提高，薄膜的刚度和抗拉强度均有所提高。

Preparation and investigation of a urethane methacrylate containing a tert-butyl terminal group in urethane/acrylate hybrid latexes

A urethane methacrylate with a tert-butyl terminal group, 2-((tert butylcarbamoyl)oxy) ethyl methacrylate (tBEM), was synthesized and incorporated into a series of homogeneous and core-shell model acrylate latexes. Unlike urethane methacrylates with linear or cyclic alkyl terminal groups, the tert-butyl group seems to preclude urethane formation, other than a direct approach of reacting tert-butyl isocyanate with 2-hydroxethyl methacrylate (HEMA) was employed. The effect of tBEM content on latex performance was investigated using minimum film formation temperature (MFFT) tester, differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), tensile tests and Fourier transform infrared spectroscopy (FTIR). Increasing the loading level of tBEM led to an increase in film stiffness and tensile strength.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
