    摘要: This invention relates to novel cyanourea compounds of the formula: ##STR1## wherein R is the organic moiety of a polyisocyanate remaining after reaction of the isocyanate groups to form cyanourea groups and n is at least 2. The compound can be polymerized at room temperature to form a polymer having the recurring structural formula: ##STR2## i.e., N,N'-biscarbamyl-N-cyanoguanidine units connected together through the R group of the carbamyl moiety and m is greater than 2, or can be cured to a thermoset material on heating above 90.degree. C.
