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.
