Patent ID: 8703111

Claim:
Thermoplastic paste with thixotropic rheology comprising: a) a block biopolymer, of formula [(A-B-C) n -D-E-D-(A-B-C) n -] m , comprising a rigid block (A-B-C) n and a flexible block (-D-E-D-), wherein: A and C are dihydroxy monomers B and D are dicarboxylic acids, E is a polymer with a hydroxyl number ≧10, n and m are numerical indices ≧1 and wherein: the rigid block, (A-B-C) n , consists of a polymer comprising ester type bonds, wherein the flexible block, (-D-E-D-), consists of a second polymer comprising a hydrocarbon chain containing ester or ether type bonds, b) a bioceramic in a proportion of 10-70% of the total weight of the thermoplastic paste, wherein A and C are 1,8-octanediol, B and D are glutaric acid, E is polyethylene glycol polymer, and the bioceramic is hydroxyapatite.
