ABSTRACT:
Ternary alloys of PVC/CPVC/alloying polymers are disclosed which make use of the unexpected results of interactions between alloying polymers and CPVC and PVC, interactions which result in higher heat distortion temperatures than predictable by linear addition of the properties of the binary blends of PVC/CPVC and PVC/alloying polymer systems. This effect allows replacement of substantial amounts of alloying polymer with a predetermined amount of CPVC without changing substantially HDT or melt viscosity. Such effects allow the use of these ternary alloys in place of binary PVC/alloying polymer systems in injection molding and extrusion applications.
