process for the preparation of a rigid vinyl chloride polymer material with better resistance to defend and shaped productsmanufactured under the vinylchloridepolymeermateriaal thus prepared.

摘要

Improved weather-resistant building products, such as house siding and the like, are made from vinyl chloride polymers containing both rutile and anatase titanium dioxide. Said compounds are rigid, high impact compounds having improved color retention, impact retention and resistance to dirt accumulation and fungus growth after weathering exposure.
