Abstract: Vinyl chloride polymers are prepared by polymerizing a monomer component that comprises vinyl chloride in an aqueous medium in the presence of a free radical-generating polymerization initiator and 0.01% to 2% by weight, based on the weight of the monomer component, of a chain-transfer agent that is a mercapto organic compound having at least one beta-ether linkage. The process can be used to produce low molecular weight vinyl chloride polymers.

Abstract: A lighted coaster for supporting beverage containers such as glasses. The improvement provides a top cover having a translucent lens and a side skirt extending downwardly to overlap a base member. The base contains batteries and a spring-biased light bulb extending upwardly to contact the underside of the lens in such a fashion that when beverage glasses are placed on the coaster, the light moves downwardly to contact a suitably disposed circuit member and actuate the light. When the beverage is removed, the light urges the cover upwardly a short distance and breaks contact with the electric circuit and turns itself off.
