Abstract:

The preliminary research on laminating polyurethane systems possessing good thermal stability with accompanying highly desirable mechanical properties is reported. In the main, two systems were observed to fulfill the first requirement, but the degree of fulfillment of the second requirement concurrent with the first has yet to be measured. These two outstanding systems were synthesized from diphenylmethane 4,4 - diisocyanate with a glycol polymer of diethylene glycol terephthalate and diphenylmethane 4,4 - diisocyanate with 3,3 bis p-hydroxy phenyl phthalide.
