TH35792A - Polyamide preparation - Google Patents

Abstract

DC60 (03/06/42) Disclosure is a process for preparing polyamide by rinsing the water extract from the extraction of The polyamide was concentrated until the extract content was not more than 85% by weight. Adding a new batch of lactam into The water content of 0.5-13% by weight and caused at least one adiabatic expansion. Model during polymerization Disclosure is a process for preparing polyamide by concentrating the rinsing-water extract from the extraction of polyamide to The amount of extracts cannot be more than 85% by weight, add lactam set. New comes down to water content from 0.5-13% by weight and induces at least one adiabatic expansion during polymerization.
