Title: Study of the aging processes in polyurethane adhesives using thermal treatment and differential calorimetric, dielectric, and mechanical techniques. I. Identifying the aging processes. II. Quantifying the aging effect

Abstract

It is shown that the thermal aging of polyurethane adhesives involves competitive mechanisms that occur simultaneously as a function of time and temperature. These mechanisms involve chain scission and formation of pseudocrystalline domains. 12 figures, 2 tables.
