Cyclic-diene Additives in Polyethylene Films and Enhanced Film Orientation Balance in Production Thereof
A method of forming a blown film comprising extruding a molten composition through a die opening to form a film; wherein the molten composition comprises at least one polyethylene and within the range from 0.10 wt % to 10 wt % of a cyclic-diene terpolymer by weight of the composition; causing the film to progress in a direction away from the die opening; cooling the film at a distance from the die opening, the distance adjusted to effect the properties of the film; and isolating a blown film therefrom.

Method for producing stretched film
The present invention is a method for producing a stretched film comprising stretching an unstretched film that is formed using a hydrogenated dicyclopentadiene ring-opening polymer at a temperature of 95 to 135 C. and a stretching ratio of 1.2 to 10, followed by heating at a temperature of 150 to 220 C. Since the thus-obtained stretched film has excellent transparency and low coefficient of linear expansion, the stretched film is suitable for not only use in optical applications but also use for electronic materials.
Resin composition and resin molded article
The present invention is a resin composition comprising a cycloolefin resin and at least two hydrogenated styrene-based thermoplastic elastomers, wherein a content of the cycloolefin resin is 50 to 90 wt % based on a total amount of the cycloolefin resin and the hydrogenated styrene-based thermoplastic elastomers, and a melt volume rate of the resin composition at 260 C. is higher than that of the cycloolefin resin at 260 C., and a resin formed article. One aspect of the invention provides a resin composition that exhibits excellent transparency, impact resistance and melt fluidity, as well as a resin formed article obtained by forming this resin composition. The resin formed article of the present invention is preferably used as a drug container, a medical instrument or the like, since it exhibits excellent transparency and impact resistance.
