CROSS-LINKABLE THERMOPLASTIC POLYURETHANES Russian patent published in 2015 - IPC C08G18/65 C08G18/67 C09D175/16 C09D175/04 C09D175/14 

FIELD: chemistry.

SUBSTANCE: invention relates to a cross-linkable mixture which includes a thermoplastic polyurethane, which contains radically polymerisable unsaturated groups at the ends of the thermoplastic polyurethane chain with average molecular weight of 5000 to 12000, which does not contain urea, isocyanurate, oxozolinyl and radically polymerisable functional side groups and which is obtained by reacting one or more polyfunctional isocyanates one or more polyfunctional polyols, one or more monofunctional alcohols or amines which contain radically polymerisable unsaturated group(s), and one or more diol chain extenders, having molecular weight lower than 400; and ethylenically unsaturated compounds, where the cross-linkable mixture does not contain any additional inactive solvent. Also described is a method of producing said cross-linkable mixture, a method of producing thermosetting material and a coating method.

EFFECT: obtaining end materials based on polyurethane cross-linked mixtures.
