Abstract
Most of the nylon 6 produced projtly.
Zia obtained by the hydrolytic initiated ring Opening polymerization of caprolactam NH(CH ) 00 catalyzsed -ith acetc; acid.t2 5l1 As any other industrial operation, th.is polymerization is characterised ’Llv a complex relation between parameters such as product quality and composit-Jon, conversion, throughput, process and reactor desirn, cost. and life-time of equipment, and energy and personnel requirements.. Since the optimization of such parameters require, most,of all, the understanding of the me-.hanism and kinetics of the process, it is important to reveal the role of such variables mainly affecting this proceos.
AlthougL numerous investigations have elucidated the polymerization equilibria, kinetics; and mechanism of 3
caprolactam (CL) under either hydro’-3
anionic orcationic initiation (34-14), little has been reported on the initiation in presence of multi-ad-ditivesp such as water with acetic acid(69)The hydrolytic-initiated polymerization of CL is charaterised by three main reactions, namely ring opening
