LOW VISCOSITY LIQUID CRYSTALLINE POLYMER COMPOSITIONS

Liquid crystalline polyesters or poly(ester-amides) having improved melt viscosity, are made by reacting the polymer with limited amounts of a compound containing specified functionality, such as hydroxyl, carboxyl, or amine. The process may be carried out in a typical polymer melt mixing apparatus...

Beschreibung
Zusammenfassung:	Liquid crystalline polyesters or poly(ester-amides) having improved melt viscosity, are made by reacting the polymer with limited amounts of a compound containing specified functionality, such as hydroxyl, carboxyl, or amine. The process may be carried out in a typical polymer melt mixing apparatus such as an extruder. The low viscosity polymer product of the claimed invention has surprising toughness and is particularly useful for encapsulation of electronic components.
