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

Technical Report ·
OSTI ID:5804352
;

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.
