thermooxidation resistance

Polymers of Phenyldiacetylenes – Functional Thermostable Additions to Industrial Resins

High thermal and thermooxidation stability of homo and copolymers of diphenyldiacetylene and p-diethynylbenzene was established. The amount of coke residue, obtained from commercial epoxy-resins, is essentially increased upon their modification with added polymers. Additions of polydiethynylbenzene to commercial olygoetheracrylates improved their thermooxidation stability.
