Weathering-resistant polymer alloys |
摘要 |
For optical applications, transparent amorphous thermo-plastics, such as polyaryl ether ketones, are of considerable interest. However, polyaryl ether ketones have inadequate UV stability and weathering resistance while amorphous polyaryl esters do not have these negative properties. The properties can be improved by means of polymer alloys, giving weathering-resistant materials from homogeneously mixed polymers which comprise at least one amorphous polyaryl ether ketone and at least one amorphous polyaryl ester.
