Abstract

PURPOSE: A composition having no tackiness in the nornal state but exhibiting tuckiness by pressing or stretching, which is prepd. by mixing a specified block copolymer with a tackifying styrene resin and molding and resulting mixt. into a film or cord.
CONSTITUTION: 100pts.wt. block copolymer of formula A-B-A (where A is a styrene polymer block; B is an isoprene-butadiene polymer block) is mixed with 150W50pts.wt. tackifying styrene resin and molded into a film or cord. The tackifying resin is a styrene resin, an arom. petroleum resin, etc. with 150pts.wt. or more tackifying resin, tackiness is exhibited in a reduced extent, while with 30pts.wt. or less, tackiness is impratically low. The composition is advantageous as an adhesive necessitating no tackifier support or releasing paper, and also advantageous in the field of the application of a adhesive sheet, etc. because of unnecessariness for a heating device, etc. Further, it has tackiness and shrinkability induced from rubber elastisity and is excellent in sealing property for a container, in relation to the field utilization of a simple packaging film.
