Abstract: A polymer concrete pipe liner is formed from a fluidized, but substantially waterless cement containing mixture applied to the pipe interior. The mixture is composed of inorganic cement particles, a liquid styrene mixture and a minor amount of one or more poly-olefinically unsaturated co-monomers. The mixture substantially excludes acrylonitrile and acrylamide. The co-monomers are preferably selected from a group including trimethylolpropane-trimethacrylate, divinyl benzene, hexadiene, and polyvinylsiloxanes. Mixing the liquid and solid components forms a slurry which is transferred to a pipe interior. Transfer properties can be controlled by particulate gradation, dissolved polymers, and rheology control additives. The pipe is then spun to centrifugally cast the liner. The composition avoids the need for high temperature curing and toxic reactive unsaturates to co-polymerize and cross-link polystyrene.

Abstract: Curable polycycloolefin resin solutions having particular utility in the fabrication of printed circuit boards are disclosed. A solvent soluble polymer is typically solution polymerized from norbornene-type monomers in the presence of a metathesis catalyst package. This polymer may then be purified by precipitation and redissolution. A curing agent, such as a high activation temperature peroxide can then be added to the solution and then this curing agent containing solution can be used to impregnate a suitable substrate such as a fiberglass cloth. The impregnated substrate can then be dried, preferably at temperatures above the glass transition temperature of the polycycloolefin but below the activation temperature of the curing agent. Then one or more prepregs can be stacked and laminated to conductive foil at a temperature high enough to activate the curing agent.
