Process for preparing benzamide polymers
Abstract
Abstract (R)N-1,4-PHENYLENE, (R)N-1,3-PHENYLENE, AND BOTH HOMOPOLYMER AND COPOLYMER PREPARATION IS DESCRIBED, INCLUDING SUITABLE SOLVENTS USEFUL FOR POLYMERIZATION AND/OR FOR FORMING SHAPED ARTICLES OF THE POLYMER. SUITABLE BASES, ADDED TO THE REACTION MEDIUM, PROMOTE THE FORMATION OF HIGH VISCOSITY POLYMER. 1,4-PHENYLENE, AND 1,3-PHENYLENE WHEREIN R IS A MONOVALENT RADICAL WHICH IS INERT IN THE POLYMERIZATION REACTION N IS A CARDINAL NUMBER FROM 0 TO 4 AND, Y AND Y'' ARE INDIVIDUALLY SELECTED FROM THE GROUP CONSISTING OF: -Y-CO-NH-Y''- WHEREIN X IS SELECTED FROM THE GROUP CONSISTING OF: O=S=N-X-CO-CL A PROCESS PREPARING BENZAMIDE POLYMERS BY REACTING MONOMERIC AROMATIC THIONYLAMINES OF THE FORMULA:
