摘要：For optical applications, transparent, amorphous thermoplastics, such aspolyaryl ether ketones, are of considerable interest. However, polyaryl ether ketoneshave inadequate UV stability and weathering resistance, while amorphous polyaryl estersdo not have these adverse properties. The properties can be improved by means ofpolymer alloys, and weathering-resistant materials made from homogeneously mixedpolymers comprising at least one amorphous polyaryl ether ketone and at least oneamorphous polyaryl ester are thus obtained.
