Process of heating caprolactam graft copolymers to increase melt strength |
| abstract |
WHEN OLEFIN-MALEIC ANHYDRIDE COPOLYMERS ARE EMPLOYED AT LOW LEVELS IN HYDROLYTIC POLYMERIZATION OF CAPROLACTAM TO YIELD GRAFTED CAPROLACTAM COPOLYMERS, THE RESULTING POLYMERS UPON HEATING IN THE SOLID STATE AT A TEMPERATURE OF AT LEAST 140*C. INCREASE IN MELT STRENGTH TO VALUES CONSIDERABLY ABOVE THE MELT STRENGTH OF CONVENTIONAL POLYCAPROLACTAM OF EQUIVALENT MELT INDEX. THE RESULTING PRODUCTS HAVING HIGH MELT STRENGTH MAY BE ADVANTAGEOUSLY USED FOR THE MANUFACTURE OF EXTRUDED AND BLOV XXX OLDED ARTICLES. |
