Abstract: A waterproofing sheet material useful for example as a free floating membrane or flashing material in roofing applications, a pond liner, or a gasketing material, composed of from about 15 wt. % to about 80 wt. % of an ingredient selected from the group consisting of:(a) homopolymers of alkadienes and substituted alkadienes(b) addition copolymers of alkadienes with unsaturated monomers(c) homopolymers of alkenes and substituted alkenes selected from the group consisting of polyethylene, chlorosulfonated polyethylene and polyisobutylene(d) resin acids and resin acid derivatives(e) highly aromatic bituminous materials, and(f) pine oiland from about 85 wt. % to about 20 wt. % of a plasticized polyvinyl butyral resin. Minor amounts of fatty acids and paraffin wax may be added to improve low temperature properties and to facilitate processing a hot melt admixture of the ingredients into a sheet.

Abstract: A dry electrostatic developer mix having improved fatigue-resistance properties, is realized by adding to the developer mix, which contains carrier particles and pigmented toner particles, molybdenum disulfide in amounts ranging from about 0.005% to about 1.0% preferably in the range of from about 0.009% to about 0.2% based on the weight of carrier particles present in the developer mixture.
