Abstract: A low-temperature insulating material which comprises polyvinyl chloride, a plasticizer, a water-containing or absorbing gel or an aqueous solution of a water-soluble polymer and an emulsifier and another low-temperature insulating material which comprises polyvinyl chloride gelled by mixing with a plasticizer and a surface-covered, water-containing hydrogel. The insulating materials are inexpensive and show excellent heat-insulating properties and excellent flexibility at low temperatures.

Abstract: Powder of ???,???-ethylenically unsaturated carboxylic acid metal salt is coated with a C10-C24 fatty acid having a melting point of at least 30 DEG C. A powder of ???,???-ethylenically unsaturated carboxylic acid metal salt, especially zinc acrylate, is useful as a component to make a solid golf ball, but is disadvantageously liable to coagulate in a rubber composition or to adhere to the roll or to the inner surface of a blender during the preparation of the rubber compound. In order to avoid such problems a powder of the metal salt is coated with the fatty acid mentioned above.

Abstract: This structural material is composed of a polyamide resin reinforced by a reinforcing material composed of continuous filaments and/or long fibres. The reinforcing material is surface-treated with a surface-treatment agent for nylon, soluble in alcohol and/or water. The specific viscosity (eta) of the polyamide resin is more than 1.8 poise. The amount of reinforcing material used is 10-80 wt.% of the polyamide resin. The structural material is shaped as a stick or a tennis racket. The structural material is produced by means of a polymer casting method composed of the following processes: (1) The surface treated fibrous reinforcing material is arranged in a specific shape. (2) The arranged material is placed in a mould. (3) A molten omega-lactam containing a polymerisation catalyst and an initiator is introduced into the mould. (4) The reinforced polyamide resin is obtained by heating the mould.

Abstract: A process for preparing a fiber reinforced plastic article by a reaction injection molding method, comprising the following steps; (a) winding reinforcing fiber around a flexible tube, (b) placing it in a mold, (c) either pouring a foaming agent in said flexible tube followed by foaming and curing it, or pouring an uncured foam followed by curing it, and (d) injecting a reaction-injection-molding composition between said mold and said flexible tube to cure. The article may be a shaft of a golf club or a frame of a tennis raquet.
