POLY (BLOCK-PHOSPHONATO-ESTER) AND POLY (BLOCK-PHOSPHONATO-CARBONATE) AND METHODS OF MAKING SAME

摘要

Compositions including poly(block-phophonato-esters) or poly(block-phosphonato-carbonate) and a process for making them from oligomeric phosphonates and/or polyphosphonates and polyester and/or polycarbonates are disclosed. The compositions provide tough flame retardant materials and coatings.
