  A novel application of tin-based alkoxide anion for deacetylation

  摘要：

  A stannylene acetal, in the presence of CsF, is able to cleave both aromatic and aliphatic acetates rapidly and efficiently under room temperature. Control experiments indicate that both the stannylene acetal and CsF are required and play significant roles in the deacetylation process. Thus, it is likely that the tin-based alkoxide anion generated by a stannylene acetal and OF is responsible for deacetylation. (c) 2006 Elsevier B.V. All rights reserved.

  The object of the invention is to provides a process in which a high-molecular-weight &bgr;-butyrolactone homopolymer or copolymer being biodegradable, absorbable into the living body, useful as a functional polymeric material and superior in physical characteristics is produced with high yield and good productivity. This object is solved by a process for producing the homopolymer or copolymer of the invention, which comprises ring-opening polymerization of sole &bgr;-butyrolactone subjected previously to acid removal and dehydration treatment, or of said &bgr;-butyrolactone with other lactones, in the presence of a tin compound represented by the following formula (1) and/or formula (2): 1 wherein R 1 and R 2 and R 4 to R 7 independently represent an alkyl group containing 1 to 12 carbon atoms which may have a branched chain, or a cycloalkyl group containing 5 to 7 carbon atoms, or a phenyl or naphthyl group which may have a substituent group, R 3 represents an alkylene group containing 2 to 12 carbon atoms which may have a substituent group, a cyclopentane-1,2-ylene group or a cyclohexane-1,2-ylene group, and n is an integer of 1 to 10.

  本发明的目的是提供一种高分子量的β-丁内酯均聚物或共聚物的制备方法，该聚物具有生物降解性，可吸收进入生物体内，可用作功能性聚合物材料，并且物理特性优良，且产量高且生产效率好。本发明的目的通过以下制备该发明的均聚物或共聚物的方法来解决：在预先去除酸和脱水处理的单一β-丁内酯或与其他内酯混合的β-丁内酯存在下，进行开环聚合反应，反应中存在以下式（1）和/或式（2）所表示的锡化合物：其中R1、R2和R4到R7独立地表示含1至12个碳原子的烷基，可以是支链的，或者含5至7个碳原子的环烷基，或者含有取代基的苯基或萘基，R3表示含有2至12个碳原子的烷基，可以是含有取代基的环戊-1,2-亚基或环己-1,2-亚基，n为1至10的整数。
