FORMING METHOD OF NONINFLAMMABLE POLYESTER ESTER BLOCK COPOLYMERS

摘要

This new flame retardant polyetherester keeps the essential characters as elastomer and at the same time it has good flame retardant and thermal stability. This one comprises: halogenated polyol 5-20 wt.parts, polypentabromobenzyl acrylate 5-20 wt.parts, antimony trioxide 2-10 wt.parts and silica 1-10 wt.parts in the basis of polyetherester block copolymer 100 wt.parts. The above halogenated polyol gives flame retardant to the chain itself so copolymer doesn't lose its rubber-like properties and mechanical properties.
