Abstract: As starting materials for substrates for optical storage disks, cycloolefin copolymers (COC) are produced by a polymerization process in which the polymerization is terminated at a point in time at which the molar-mass distribution M w/M n is 15,000 g/mol and M w/M n less than/equal to 4 and greater than/equal to 2. The substrate is produced by thermal deformation either of a single COC having a molar-mass distribution M w/M n of

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.
