Provided are an ethylene polymer mixture, a method of preparing the same, and a molded article using the same. More specifically, an ethylene polymer mixture in which two ethylene polymers having different densities are mixed, a method of preparing the same, and a molded article having a low haze and a low heat sealing temperature using the ethylene polymer mixture, are provided.

Ethylene polymer mixture, method of preparing the same, and molded article using the same

Provided are a multilayer separator capable of improving interlayer peel strength and exhibiting excellent permeability due to a high degree of alignment, and a method of manufacturing the same. The method of manufacturing a multilayer separator includes: manufacturing a precursor film by co-extruding and molding a polypropylene based resin melt having a melt index (2.16 kg, 230&#xb0; C.) of 0.3 to 5 g/10 min and a polyethylene based resin melt having a melt index (2.16 kg, 190&#xb0; C.) of 0.1 to 1.5 g/10 min so as to be alternately laminated; and heat-treating and stretching the manufactured film, wherein a melt index ratio (A/B) of the polypropylene based resin melt (A) and polyethylene based resin melt (B) is 2 to 10.

Multilayer separator with superior permeability

Provided herein are a method for preparing a resin composition for an expandable polypropylene carbonate and an expandable polypropylene carbonate prepared therefrom. More particularly, the present invention relates to a method for preparing a resin composition for an expandable polypropylene carbonate capable of using supercritical carbon dioxide as a foaming agent and preparing a foam having excellent moldability by an appropriate foaming method, and an expandable polypropylene carbonate prepared therefrom. The expandable polypropylene carbonate capable of having high magnification, excellent thermal stability, and dimensional stability may be prepared by using the resin composition according to the present invention.

Method for preparing resin composition for expandable polypropylene carbonate and expandable polypropylene carbonate prepared therefrom

The present invention relates to a multilayer film coextruded from an aliphatic polycarbonate and polylactic acid-based polymer and a method for producing the same. According to the present invention, a multilayer film having excellent adhesive property can be manufactured even without a separate adhesive layer.
