LIQUID MIX FOR REACTIVE INJECTION MOULDING, THE METHOD OF MANUFACTURE PRODUCED REACTIVE INJECTION MOULDING BODY AND DERIVED REACTIVE INJECTION MOULDING BODY Russian patent published in 2017 - IPC C08G61/08 B29C45/00 C08F4/78 

FIELD: chemistry.

SUBSTANCE: liquid mix is described for reactive injection moulding containing monomer on the basis of norbornena, except that it contains 3-100 wt % of exo-dicyclopentadiene, metathesis polymerization catalyst, which includes tungsten as the central metal, activator and essential compound represented by the formula where R¹-R⁴ independently represent alkyl group has a 1-6 carbon atoms. Referred to the liquid mixture for reactive injection moulding includes activator and essential link in the molar ratio (essential connection/activator) of 0.7/1-30/1. The method of manufacture produced reactive injection moulding product incorporating reactive injection moulding stage, which involves exposure above the liquid mixture bulk polymerization within the form, is also described. The formation of the product obtained using the above method is described.

EFFECT: improving the surface condition and improving the strength of the moulded product.
