Abstract
Complex microspheres consist of polysiloxane and vinyl polymers which are unistructurally mixed together and substantially free of covalent bonds therebetween. Polysiloxane and vinyl polymer are contained at ratio of 97/3.about.30/70 by weight, the average diameter of the complex microspheres is 0.05.about.30 .mu.m, the standard deviation of their particle size is 1.0.about.2.5, and the ratio between their major and minor axes is 1.0.about.1.2. Thermoplastic films containing such complex microspheres at a specified rate have improved lubricity and anti-blocking properties.
