Abstract
Modified titanium oxide is prepared by polymerizing a mixture of vinyl chloride and a carboxylic monomer such as 10-undecenoic acid in the presence of titanium oxide. The thus obtained, modified titanium oxide is mixed with a vinyl chloride resin, typically, polyvinyl chloride to give a vinyl chloride resin composition having an improved weatherability and being substantially free of serious drawbacks accompanying the addition of conventional titanium oxide such as plating out during extrusion and decrease in extrusion throughput.
