Abstract: Metal-containing organic flow-modifying agents comprising a major proportion of a non-Newtonian colloidal disperse system containing metal-containing particles, dispersing medium and an organic compound having both a hydrophobic and a polar substituent and a minor proportion of polymeric resin which is present as a random dispersion of particles in a non-solvated form are useful in modifying the flow properties of plastic materials. Specific examples of the disperse system are those comprising calcium carbonate particles dispersed in a mineral oil dispersing medium in the presence of a calcium petrosulfonate; an example of the resin is finely divided polyethylene. These agents are useful for modifying the flow properties of plastic materials such as filled asphalt systems.

Abstract: Substrates such as polyethylene terephthalate copolymers are treated with polyester adhesives containing flame retardant polymers. The adhesive/polyethylene terephthalate composite possesses improved resistance to combustion.
