Halogen-Containing Fire Resistant Copolyesters

Abstract:

Copolyarylates based on a mixture of 2,2-bis (4'-hydroxyphenyl) propane, 3,3-bis (4'-hydroxyphenyl) phthalide, terephthalic and isophthalic acid chlorides and 3,5-dibromo-p-hydroxybenzoic acid chloride were synthesized by low-temperature acceptor-catalytic polycondensation. To study the structure of the obtained polyesters and study the physical and mechanical properties, infrared spectroscopy, elemental, thermogravimetric, X-ray structural and thermomechanical analyzes were used. The obtained polymers have high values ​​of strength characteristics, thermal and heat resistance, good fire resistance.
