| titleOfInvention | Chlorinated polyvinyl chloride rigid compound and articles derived therefrom |
| abstract | CPVC compositions, pipe, and a method of preparing a pipe are disclosed and comprise CPVC having 63% to 70% by weight chlorine and preferably 65% to about 69% chlorine; a high rubber impact modifier comprising a graft copolymer of a rubbery polydiene and one or preferably more than one hardening monomer selected from a group consisting of a vinyl aromatic monomer, a (meth)acrylate, and a (meth)acrylonitrile monomer including mixtures. Said graft copolymer exhibits a Shore D hardness of less than about 64, and preferably between about 35 and 45; and a chlorinated polyethylene containing between 30% and 40% chlorine by weight, compression molded placques derived from the powder composition exhibit a minimum tensile strength, modules, izod impact strength, Tg and dynamic thermal stability specified herein. A pipe extruded directly from said composition meets ASTM-D2846 and exhibits unexpected ductility down to 20°F (-6.6°C) under fixed drop dart impact testing. The invention is useful for example in articles such as hot and cold water distribution system components installed in seasonal environments. |
