One or more silicon atoms of the polysiloxane is substituted with an alkylene group terminating with a silyl group containing three substituents selected from the group consisting of hydroxy, halo, alkoxy, acetoxy, and mixtures thereof. These treated particles are blended with organic polymers to form a polyethylene polymer matrix having dispersed therein at least 55 wt % polysiloxane modified titanium dioxide particles.
