Abstract: The invention relates to a rigid, single- or multilayer, unoriented or monoaxially or biaxially oriented film in which at least one layer contains a cycloolefin copolymer, characterised in that the cycloolefin copolymer has an intrinsic modulus of elasticity Ei which has the following dependence on the glass transition temperature Tg: Ei = (0.0025 GPa/@C] x Tg[@C]) + B[GPa] where B = 2.93 to 3.19.i

Abstract: A glass-fibre-reinforced cycloolefin polymer material comprises from 1 to 99% by weight of at least one cycloolefin polymer, in particular a norbornene-ethylene copolymer, and from 99 to 1% by weight of glass fibres. The absolute value for the refractive index difference (refractive index of glass of glass fibres minus refractive index of cycloolefin polymer) is at most 0.015 for each cycloolefin polymer, and the refractive index of the glass fibres is in the range from 1.510 to 1.560. The materials have good mechanical properties and good light transparency. The glass fibres employed preferably contain no sizes.

Abstract: Polymers of polycyclic olefins such as, for example, norbornene or tetracyclododecene, or copolymers of polycyclic olefins with cycloolefins and/or 1-olefins are obtained without ring opening, in high space-time yield, with high cycloolefin incorporation rate and at industrially favourable polymerisation temperatures by a bulk polymerisation in which the catalyst used consists of an aluminoxane and of a stereorigid, chiral metallocene compound of an element of groups IVb to VIb, where the hydrocarbon radicals forming the sandwich structure are different.

Abstract: For optical applications, transparent, amorphous thermoplastics, 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 adverse properties. The properties can be improved by means of polymer alloys, and weathering-resistant materials made from homogeneously mixed polymers comprising at least one amorphous polyaryl ether ketone and at least one amorphous polyaryl ester are thus obtained.

Abstract: HOE: 90/F 009 Weathering-resistant polymer alloys For optical applications, transparent amorphous thermoplastics, such as polyaryl ether ketones, are of considerable interest. However, polyaryl ether ketones have inadequate W 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.
