NOVEL COMPOSITION OF POLYISOCYANATE AND POLYETHER MONOAMINE Russian patent published in 2013 - IPC C08G18/10 C08G18/32 C08G18/48 C08G18/76 C08G18/79 C08L75/04 C08K5/21 

FIELD: chemistry.

SUBSTANCE: invention relates to use of a composition obtained by reaction of polyisocyanate with index 100-250, which is diphenyl methane isocyanate, optionally containing a homologue which contains 3 or more isocyanate groups, and/or a version of such a diisocyanate with monoalkylether of polyoxyalkylene monoamine having average molecular weight of 550-3000 and content of oxyethylene higher than 50% by weight, calculated based on the weight of monoamine and an alkyl group having 1-4 carbon atoms as a plasticiser in thermoplastic and thermosetting materials which contain less than 50% hard units, and containing a certain number of urethane and/or urea groups. The invention also relates to a method of producing a plasticised thermoplastic or thermosetting material with content of hard units of less than 50%, which contains a certain number of urethane and/or urea groups, using said composition, as well as the material itself.

EFFECT: novel composition which is suitable as a plasticiser, is liquid at atmospheric pressure, does not migrate or is not released onto the surface of materials containing a certain number of urethane or urea groups, and is more effective than earlier urethane plasticisers.
