  • Patent number: 4987189
    Abstract: New polycaprolactam-based polymer compositions have been prepared by polymerising caprolactam in the presence of a quantity of nitrile rubber not exceeding 25% by weight of the total mixture weight, and preferably 5-20% by weight.The polymerisation is conducted in the presence of anionic initiators and anionic polymerisation activators.The new compositions obtained are extremely uniform, and have physical and elasticity characteristics which substantially coincide with nylon-6. There resistance to impact and deformation is however substantially higher.
    Type: Grant

  • Patent number: 4093677
    Abstract: Novel block copolymers suitable to manufacture permanently antithrombogenic prosthetic devices are obtained by first preparing a polyamide-amine prepolymer ##STR1## WHEREIN R.sub.1 and R.sub.2 are alkyl or hydroxy-alkyl radicals with 1-6 carbon atoms, R.sub.3 and R.sub.4 are alkyl radicals with 1-6 carbon atoms, R.sub.5 is an alkenyl radical with 1-12 carbon atoms, or together with R.sub.1, R.sub.2 and R.sub.3, R.sub.4 respectively and the nitrogen atoms to which it is linked, it forms an unsubstituted or substituted piperazine ring and then polymerizing at least one monomer suitable to form thermoplastic addition or condensation polymers in the presence of the polyamide-amine prepolymer.
