我的一段英译汉译文,请各位讲评? 网上找到一份专利文献,大家可以探讨一下back-addition到底是什么?大概原文后边的polymerization 就是来解释back-addition的。 according to the invention, the prepolymer formed by the reaction of components (i), (ii) and (iii) is reacted with amino alcohols (iv) so that the nco groups remaining in the prepolymer are at least partly reacted with (iv). amino alcohols containing a primary or secondary amino group are particularly suitable for this reaction of the nco-terminated prepolymers, which is also known as " back-addition ". compounds containing a tertiary amino group are also suitable. low molecular weight amino alcohols are preferred, those containing from 2 to 40 carbon atoms and preferably from 2 to 12 carbon atoms being particularly suitable. ............... 文章来源[url=http://203.208.39.132/search?q=cache:jmtvzzegduoj: /patent/bonding ... ymerization& ;cd=36&hl=zh-cn&ct=clnk&gl=cn&st_usg=alhdy29f4oas_karde1tf-1g8oig0mbkmq]http://203.208.39.132/search?q=cache:jmtvzzegduoj: /patent/bonding ... ymerization& ;cd=36&hl=zh-cn&ct=clnk&gl=cn&st_usg=alhdy29f4oas_karde1tf-1g8oig0mbkmq[/url]查看更多
