摘要：
The influence of glasstransition on the kinetics of changes in rheological characteristics of mixtures on the basis of carbamide-formaldehyde oligomers during curing has been studied. Above the glass-transition temperature, the cure rheokinetics of carbamide-formaldehyde resin is characterized by autoacceleration. In glassy material, the reaction of formation of transverse bonds is significantly retarded.
