PROCESS AND APPARATUS FOR CONTINUOUS PRODUCTION OF CROSSLINKED POLYMER

摘要

A continuous production process for a cross-linked polymer is disclosed. The process comprises the following steps: continuously mixing an uncross-linked polymer, which has been fed in a liquid form through a feed line (line A), and a cross-linking agent, which has been fed in a liquid form through another feed line (line B), together at a mixing junction (M) such that the uncross-linked polymer is allowed to continuously undergo a cross-linking reaction; and continuously discharging and collecting the resulting cross-linking reaction product as the cross-linked polymer through a discharge line (line C). Also disclosed is a production apparatus having such feed lines, mixing junction and discharge line. According to these production process and apparatus, cross-linked polymers each of which can achieve high water absorption can be continuously produced with high productivity. <IMAGE>
