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: Cycloolefin polymer molding composition of improved stability to chemical degradation. A cycloolefin polymer molding composition which comprises organophosphorus compounds of the formula IX R13-¢P(OR14)2!u (IX) of the formula X (X) or of the formula XI (XI) if appropriate in addition to other additives, shows an improved stability to chemical degradation. The organophosphorus compounds used according to the invention maintain the melt viscosity of the molding composition at the highest level (very small deviation from the starting value). They furthermore lead to the best initial colors of test specimens and to a relatively low change in color after kneading experiments.

Abstract: A polymer alloy contains at least one cycloolefin polymer and/or at least one polyolefin and a block copolymer as phase promoter, which has different contents of monomers (norbornene derivatives and cycloolefins and/or acyclic olefins) in the individual blocks. To prepare the alloy, the individual polymers are combined and processed at elevated temperature under the action of shear forces.

Abstract: HOE 92/F 111K Polymer blends of cycloolefin polymers and polyolefins For producing 100 parts by weight of a polymer blend 0 to 95 parts by weight of a finely divided polyolefin, 0 to 95 parts by weight of finely divided cycloolefin polymer and 0.1 to 99 parts by weight of a blockpolymer (which consists of monomeric units derived from norbornen and monomeric units derived from aliphatic monocycloolefins CnH2n and/or aliphatic 1-olefin, such as ethylene or propylene, are mixed and the mixture is processed under heat and shear forces. The block copolymer acts as phase mediator and contains in different blocks different proportions of the monomer units used.
