Title:
PREPARATION OF POLYPHOSPHONATES VIA TRANSESTERIFICATION WITHOUT A CATALYST
Document Type and Number:
WIPO Patent Application WO2005121220
Kind Code:
A3
Abstract:
Disclosed are embodiments of polyphosphonates produced via a transesterification process that does not required the use of a catalyst, and methods related thereto. Due to the elimination of the catalyst, these polyphosphonates exhibit a unique and advantageous combination of properties, such as fire resistance, improved heat stability, toughness and processing characteristics. Also disclosed are polymer compositions that comprise these polyphosphonates and at least one other polymer, wherein the resulting polymer compositions exhibit flame retardant properties. Further disclosed are articles of manufacture produced from these polymers, such as fibers, films, coated substrates, moldings, foams, fiber-reinforced articles, or any combination thereof.
