Chlorinated Polyvinylchloride CPVC

Chlorination of polyviitylchloride increases its tensile, compression and flexural strengths by about 30%. Impact strength more than doubles and even elongation doubles. Considering this, plasticization will most likely act in the opposite direction and reverse these ctonges important in some applications. In addition, plasticization lowers the heat distortion temperature that in many applications of chlorinated polyvinylchloride, CPVC, is a critical performance characteristic. ... 

These data indicate that the polymethylmethacrylate (PMMA) surface was basic and that chlorinated polyvinylchloride (CPVC) and polyvinyl flouride (PVF) were both acidic and basic. Polypropylene was nonpolar, but corona treatment led to formation of acidic and basic sites. Another example of the effect of treatments on the surface of a plastic is shown in Table 6 (49). The surface activity of PVF was increased by plasma treatment, whereas corona treatment... 

Polyvinylchloride (PVC) is commercially the most signihcant member of the family of vinyl resins. The other important members of this group are chlorinated-PVC (CPVC) and polyvinylidene chloride (PVDC). PVC is one of the most widely used, commodity type thermoplastics with an annual consumption of over 5 Mton/y in the USA. The excellent versatility of PVC is attributed to its blending capability with a variety of plasticizers, additives and fillers to yield products ranging from very flexible to very rigid types. In addition, PVC has a low cost advantage and a reasonably good balance of properties, which...
