Abstract:
A process for producing microstructured components comprising as material at least one cycloolefin copolymer comprising 0.1-100% by weight, based on the total mass of the cycloolefin polymer, of polymerized units derived from at least one polycyclic olefin of the formula I, II, IIâ€², III, IV, V or VI wherein R1, R2, R3, R4, R5, R6, R7 and R8 are identical or different and are each a hydrogen atom or a C1-C20-hydrocarbon radical wherein identical radicals R1 to R8 in the various formulae 1 to VI may have different meanings, and n is from 0 to 5, and from 0 to 99.9% by weight, based on the total mass of the cycloolefin copolymer, of polymerized units derived from one or more acyclic olefins of the formula VII wherein R9, R10, R11 and R12 are identical or different and are each a hydrogen atom, a linear, branched, saturated or unsaturated C1-C20-hydrocarbon radical and from 0 to 45% by weight, based on the total composition of the cycloolefin copolymer, of polymerized units derived from one or more monocyclic olefins of the formula VIII wherein m is from 2 to 10, and forming the microstructured components by means of laser radiation.
