Abstract
A composition of matter comprising a blend of CPVC having a chlorine content of between about 64% and 71% by weight and poly(ethylene oxide) in a ratio of approximately 0 to 20 parts poly(ethylene oxide) per 100 parts chlorinated poly(vinyl chloride). The resulting immiscible blend demonstrates improved impact resistance, improved shear viscosities properties and relatively unaffected strength properties. Optionally, glass fiber in either mat or loose glass form may be included in the blend of CPVC and PEO either by incorporation into the blend or by lamination of mats of glass fiber with layers of the blend of CPVC and PEO to provide even more enhanced tensile and other physical strength properties.
