Mechanisms of Char Formation during Flammability.
Abstract
Research was conducted on high char forming polymers systems. Work has established two principles for high char formation at elevated temperatures: the formation of thermally stable crosslinks and the formation of thermally stable ring structures. This research has dealt primarily with the latter and a larger part of it has concentrated on substituted aramids. Considerable interest in recent years has been devoted to the study of polymers which are flame resistant. With sufficient heat and oxygen, most organic polymers will burn. Polymer flammability is related to a number of factors such as polymer composition and structure, bond strength, char yield, nature of pyrolysis products, and exposure environment. Keywords: Aromatic polyamides; Nitro containing aramids; Nitrile Containing aramids; Halogenated aromatic polyamides.
