LIQUID FEED PIPE AND METHOD OF MANUFACTURING POLYALLYLENE SULFIDE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To efficiently and inexpensively manufacture and supply polyallylene sulfide superior in quality. SOLUTION: This method of continuously manufacturing polyallylene sulfide by the polymerization condensation of alkali metal sulfide and a dihalogenated aromatic compound comprises distributing a reactive mixed liquid containing the polyallylene sulfide in a liquid feed pipe which is formed by connecting a pipe inner diameter and an inner ring diameter of a seal material via a pipe joint having the same size.
