摘要： A PHENOL WHICH IS UNSUBSTITUTED AT THE POSITION PARA TO THE HYDROXY GROUP OR UNSUBSTITUTED AT AT LEAST ONE OF THE POSITIONS ORTHO TO THE HYDROXY GROUP IS DISSOLVED IN A SOLVENT, IN THE ABSENCE OF HYDROGEN SULFIDE AND CATALYSTS, AND WHILE COOLING TO A TEMPERATURE BELOW 30* C. IS REACTED WITH DISULFUR DICHLORIDE. THE SOLVENT IS AN ACID AMIDE WHOSE NITROGEN ATOMS ARE COMPLETELY ALKYLATED. POLYTHIOBISPHENOLS ARE OBTAINED IN HIGH YIELD.

摘要： AN IMPROVED PROCESS FOR THE PREPARATION OF SHAPED ARTICLES WHEREIN A POLYAMIDE IS FORMED BY THE POLYCONDENSATION OF A CORRESPONDING DIAMINE AND A CORRESPONDING ACID CHLORIDE IN A SOLVENT. THE SOLVENT HAVING THE FORMULA:

R-N
WHEREIN R IS AN ALKYL RADICAL HAVING 1-4 CARBON ATOMS AND N IS A WHOLE NUMBER BETWEEN 5 AND 7.
