A benzocyclobuten-4-yl acrylate(1) monomer was prepared by esterification of 4-hydroxybenzocyclobutene with acryloyl chloride.The radical homopolymerization of 1 and copolymerization of 1 with styrene or n-butyl acrylate were carried out to produce linear polymers 2a,2b and 2c.Heating of these linear polymers under thermal initiation gave corresponding cross-linked polymers 3a,3b and 3c.The ring-opening reaction in the cross-linking process was confirmed by on-line infrared spectra.Differential scanning calorimetry showed that the glass transition temperatures of linear polymers 2a and 2b were 83.2℃and 68.1℃,respectively.Thermogravimetric analysis of the cross-linked polymers showed that they all exhibited good thermal stability.

摘 要：目前，低年级很多小学生不太喜欢英语口语作业，总是马虎对待，甚至不当一回事。其实，在笔者看来，只要方法得当，引导正确，比如，可以采取“尝试‘小老师’轮流制”“实行小组互相评价”“开展英语课外活动”等方法，让小学生爱上口语作业并不难。 关键词：“小老师”轮流制；小组互相评价；英语课外活动 中图分类号：G427 文献标识码：A 文章编号：1992-7711（2013）23-038-1 一

摘 要：要学好一门外语，学生就必须在一定阶段掌握好一定数量的词汇，小学英语词汇教学直接影响学生听、说、读、写各项技能的发展。笔者认为词汇教学“生活化”是促进学生高效掌握词汇的有效方法之一。 关键词：小学英语；词汇教学；生活化 中图分类号：G427 文献标识码：A 文章编号：1992-7711（2013）23-076-1 一、“生”——生动有趣 1.导入激发兴趣。俗话说“Well begu
