  • Linear blocker polymer
    Publication number: 20060063909
    Abstract: Linear block polymer according to Formula (1) wherein R1 is derived from a diamine, e.g. ethylene diamine, 1,2-diamino propane or 1,3-diamino propane; R2 is derived from an aromatic diisocyanate; R3 is derived from an esterdiol; R4 is derived from dibutyl amine or ethanolamine; Where 08, wherein the monomers from which R2 and R3 are derived from are added in such amounts that the molar ratio between R2 and R3 is larger than 2:1.

  • Film for medical use, consisting of linear block polymers of polyurethane and a method for the production of such a film
    Patent number: 6627258
    Abstract: Porous films for medical use are provided comprising linear block polymers of polyurethane and urea containing hydrolyzable ester groups which are spaced along the carbon chain backbone of the film predetermined distances, so that upon hydrolysis of the ester groups fragments of the polymer are formed which have a size which can be secreted from the body of a mammal, the porous film including pores having an average pore size of up to 600 &mgr;m.

  • Shaped bodies for use as implants in human medicine and method for the production of such shaped bodies
    Patent number: 6436136
    Abstract: Implants are disclosed for use in humans having a rigidity comparable to human bone comprising polyurethane with hydrolysable ester linkages which are spaced apart to provide hydrolysis fragments which are sufficiently small to be resorbed in the human body, the polyurethane comprising a network polymer which is substantially free of urea groups. Methods for the production of such implants are also disclosed.
