双酚A型聚醚醚酮水基分散液及涂层的制备

Aimed at making high-performance coatings,the UV-crosslinking behavior of bisphenol A-type poly(ether ether ketone) were studied. A homogeneous aqueous dispersion of this soluble poly(ether ether ketone) was successfully obtained through polymer emulsion formation and then the solvent evaporation. The uniform particles(～150 nm) could be formed when mass fraction of the polymer in chloroform was ranged from 3% to 25%. The coating could be prepared via spray-coating method from above concentrated aqueous dispersion and some processing aids. We found the UV crosslinked layers had better hardness,adhesions and solvent-resistance than the ones without UV irradiation.

西欧聚氨酯胶粘剂发展方向

2001年西欧聚氨酯胶粘剂和密封剂需求量估计23．3万吨，占整个聚氨酯组合料的7％。这部分组合料市场竞争剧烈，靠其自身技术发展为动力，求得市场空间。预计2006年胶粘剂产量将达到16．67万吨，密封剂为9．11万吨。年均增长分别约为1．9％和2．2％。这归因于西欧聚氨酯原料生产基地实力雄厚，终端产品市场积极向外开拓。
