摘要： A method of molding pre-foamed synthetic resin particles is described, which comprises increasing the pressure in a mold cavity with a pressurized gas, charging the mold cavity with pre-foamed synthetic resin particles as they are compressed with a gas pressurized to a pressure higher than the pressure in the mold cavity and heating the charged pre-foamed synthetic resin particles with steam so that they are fused together or expanded and fused together to form a foamed molded article, wherein a pressure detector is provided in a conduit for conveying the pre-foamed synthetic resin particles into the mold cavity as they are carried by the pressurized gas or at an inlet portion of a charging port leading to the mold cavity, and the supply of pre-foamed synthetic resin particles into the mold cavity is stopped when the pressure detected by the detector exceeds the pressure in the mold cavity by a predetermined amount. A blow-filing gun apparatus suitable for use in the practice of the molding method is also described.

摘要： A method of producing a polypropylene resin molded product from foamed polypropylene particles is disclosed, which comprises introducing a pressurizing gas into foamed polypropylene particles having closed cells so that the particles have an internal gas pressure of from 0.3 to 2.5 Kg/cm.sup.2 G, charging the particles in a mold cavity while compressing the particles with a pressurizing inorganic gas until the initial apparent volume of the particles is reduced to 50 to 99%, removing the gas from the mold cavity while keeping the foamed particles in a compressed state, and introducing steam in the cavity to cause adhesion of the compressed foamed particles. The method produces a molded product having satisfactory appearance and excellent adhesion among particles in a shortened molding cycle.

摘要： Novel composite polymer particles are obtained, under specified conditions, by preparing an aqueous suspension comprising 100 parts by weight of propylene polymer particles, 5 - 200 parts of a vinyl or vinylidene monomer, and a specific polymerization initiator; heating the aqueous suspension to impregnate the propylene polymer particles with the monomer; and then raising the temperature of the aqueous suspension to complete polymerization of the monomer. The resultant composite polymer is improved in molding, mechanical, chemical and physical properties and is useful as molding or forming material as it is or as a blend with another polymeric material.
