Novel poly(keto-esters) having carbonyl and oxycarbonyl units randomly combined with linking units derived from olefinic monomers to form an essentially straight-chain polymer backbone are provided. The poly(keto-esters) are produced by converting a portion of the carbonyl functionality of a polyketone to oxycarbonyl groups. The conversion is achieved by reacting the polyketone with an organic peroxyacid in an inert liquid medium at a temperature from -20°C. to 150°C.
本发明提供了具有羰基和氧羰基单元的新型聚(
酮酯),其羰基和氧羰基单元与来自烯烃单体的连接单元随机结合,形成基本直链的聚合物主链。这种聚
酮酯是通过将聚酮的部分羰基官能团转化为氧羰基而制成的。这种转化是通过在惰性液体介质中,在 -20°C 至 150°C 的温度下使聚酮与有机过氧酸反应来实现的。
