  Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition a quinone methide polymerization retarder and an ammonium salt. In a mixture, the ammonium salt improves the efficacy of the quinone methide polymerization retarder and provides greater antipolymerant activity. In turn, the mixture reduces or prevents apparatus fouling and improves the purity of monomer streams.

  Polyurethane composites and methods of preparation are described herein. The methods of making the polyurethane composite can include mixing (1) at least one isocyanate selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (2) at least one polyol, (3) an inorganic filler, and (4) an evaporative coolant in an extruder to form a mixture. The method also include extruding the mixture into a mold cavity, generating heat in the mold cavity from the reaction of the at least one isocyanate and the at least one polyol, and allowing the evaporative coolant to migrate to an interface between the mixture and the interior mold surface. The temperature of the mixture causes evaporation of the evaporative coolant at the interface thereby removing heat at the interface. Suitable evaporative coolants for use in the methods of making the polyurethane composites include hydrofluorocarbons and hydrochlorofluorocarbons.
