    摘要: In a process for melting, extruding, and forming a thermoplastic synthetic resin, wherein a deckle mounted on a die device of an extruder is moved lengthwise of a slit in the die to thereby vary the length of the slit and to adjust the width of a flat film being extruded, the improvement comprising stopping the leaking of the molten resin around the deckle portion by forcibly cooling the deckle with a cooling medium, such as air, water or the like, so as to increase the viscosity of the molten resin around the deckle, whereby a decreased fluidity of the molten resin occurs.

    摘要: A composite heat-insulating material and a process for the production thereof are described. This material is of the structure that an olefin- or styrene-based resin sheet and a urethane foam material are laminated on each other with an adhesive containing: (A) 20 to 100% by weight of a water-soluble polyimine compound selected from the group consisting of polyethyleneimine, poly(ethyleneimine-urea), and a polyaminepolyamide/ethyleneimine adduct, and (B) 80 to 0% by weight of a nitrogen atom-containing cationic or amphoteric polymer. This composite heat-insulating material is very suitable for use as a lining material for a refrigerator, for example.
