摘要:
The invention is directed to polyaramid polymers, comprising repeat units of the condensation product of a fluorovinylether functionalized aromatic diacid chloride and an aromatic diamine, and methods to make said polyaramid polymers. The polymers of this invention are useful as high strength fibers or solution cast films with reduced surface susceptibility to oil.
摘要:
Disclosed are fluorovinyl ether functionalized aromatic diesters and derivatives thereof. The compounds disclosed have utility as functionalized monomers and comonomers in polyesters, polyamides, and the like. It has been found that incorporation of the monomers into polymers provides improved soil resistance to shaped articles produced from the polymers.
