Abstract:
A process is disclosed for direct extrusion of an acrylic polymer highly filled with aluminum trihydroxide wherein a lubricant is introduced to permit the composition to be extruded at a temperature below about 200° C.
Abstract:
A precursor composition to formation of a solid composite contains a glassy polymer, a step-growth polymer, a polymer or oligomer which is miscible with the glassy polymer and particulate filler.
Abstract:
A highly filled, extruded solid surface sheet composite which has improved heat resistance, solvent resistance, and mar resistance by combination of glassy polymer and semi-crystalline polymer.
