Research output: Patent

Abstract

Polyureas are produced by reaction injection moulding. The process comprises reacting in the mould: (i) a polysocyanate compound; (ii) a polyamine chain extender having at least two sterically hindered amino groups provided one on each of two ring systems connected directly or indirectly to each other; (iii) a further amino compound having at least two amino groups connected by a flexible chain, wherein the HS % value (as herein defined) of the reactants is at least 60 % and the initial temperature of the mould surface at the commencement of moulding is at least 90°C.
