Abstract:
1. A composition consisting of a plastic selected from the group consisting of polyethylene, polypropylene and polybutylene, having dispersed therein a pigment comprising titanium dioxide particles covalently bound to a neopentyl(diallyl)oxy trineodecanoyl titanate coupling agent, the neopentyl(diallyl)oxy group of the coupling agent being dissociated from the covalently bound coupling agent, wherein the coupling agent thermally desorbs from the titanium dioxide particles over a temperature range of from about 300° C. to about 500° C., and wherein the trineodecanoyl titanate group imparts hydrophobicity to the titanium dioxide particles and improved dispersability of the titanium dioxide particles in the plastic.
