Abstract
A method for producing thermosetting polyurethaneafter transformation from thermoplastic polyurethane with a hydrolyzable organo-silane which is grafted onto macromolecules of said thermoplastic polyurethane by means of a bonding agent. Said organo-silane has general formula (I), wherein R,R,R=aliphatic alkyl, aromatic alkyl; n>1; R4 is an organic radical which can react with said bonding agent which comprises at least two isocyanate functions and the thermoplastic polyurethane obtained can, after transformation, become automatically cross-linked by coming into contact with water molecules in order to become thermosetting. The invention also relates to a product which can be obtained according to the inventive method.
