聚酮的合成与性质

Synthesis Method and Properties of Polyketones

介绍了以一氧化碳和乙烯为主要原料经过催化共聚合,合成聚酮共聚物的方法以及聚酮共聚物的主要物理、化学性能。与结构相似的聚乙烯相比,聚酮共聚物具有熔点高、黏附力强、较好的光和生物降解性能等优点。可利用共聚物主链上的羰基改性聚酮共聚物,制成功能高分子材料和具有光活性的高聚物。优异的物理、化学性能和便宜的原材料来源使得聚酮共聚物的研究和应用受到越来越多的关注。

Using carbon monoxide and ethylene as raw materials, the synthesis methods and the physical and chemical properties of polyketones （PK） were introduced in this paper.Comparing with PE, PK copolymers had a lot of advanced properties such as higher melting temperature, better adhesion,the possibility of photo - and biedegradation, the possibility of modifying the copolymers on the carbonyl groups to prepare functional polymers and so on. The authors indicated that since the low cost for carbon monoxide and ethylene and the better properties, the investigation and application of PK copolymers would be paid much attention.
