The present invention provides a transition metal compound, a catalyst composition comprising same, and a method for producing an olefin polymer using the catalyst composition. A transition metal compound having a specific functional group at a specific position, according to the present invention, has high solubility and catalytic activity, and thus a method for producing an olefin polymer by using said transition metal compound can produce an olefin polymer having excellent physical properties through a simple process.

Transition metal compound, catalyst composition comprising same, and method for producing olefin polymer using catalyst composition

Provided is a resin composition for paper-coating comprising aliphatic polycarbonate having an average molecular weight of 30,000 to 300,000 obtained by reaction of one or at least two different kinds of epoxide compounds selected from a group consisting of (C2-C10)alkylene oxide substituted or unsubstituted with carbon dioxide, halogen, or alkoxy; (C4-C20)cycloalkylene oxide substituted or unsubstituted with halogen or alkoxy; and (C8-C20)styrene oxide substituted or unsubstituted with halogen, alkoxy, alkyl or aryl, wherein it contains 0 to 40 weight % of polyolefin-based resin such as polyethylene or polypropylene, based on the total amount of the composition. In addition, the present invention relates to a paper coating method of extrusion-coating the resin composition for paper-coating on paper at 130 to 250&#xb0; C. to manufacture a coated paper.

Resin composition for high barrier paper-coating

Provided is a poly(alkylene carbonate) resin composition having superior low-temperature resistance, including: a) a poly(alkylene carbonate) resin prepared by copolymerization of carbon dioxide and at least one epoxide compound selected from the group consisting of (C2-C20)alkyleneoxide substituted or unsubstituted with halogen, (C1-C20)alkyloxy, (C6-C20)aryloxy, or (C6-C20)ar(C1-C20)alkyloxy; (C4-C20)cycloalkyleneoxide substituted or unsubstituted with halogen, (C1-C20)alkyloxy, (C6-C20)aryloxy or (C6-C20)ar(C1-C20)alkyoxy; and (C8-C20)styreneoxide substituted or unsubstituted with halogen, (C1-C20)alkyloxy, (C6-C20)aryloxy, (C6-C20)ar(C1-C20)alkyloxy, or (C1-C20)alkyl; and b) any one or two or more partially aromatic polyesters selected from polyester based on aliphatic and aromatic dicarboxylic acid and an aliphatic dihydroxy compound, and aliphatic polyesters prepared from aliphatic dicarboxylic acid and aliphatic diol.

Aliphatic polycarbonate/polyester polymer resin composition having superior low-temperature resistance

Provided is a molded body in which at least one surface layer made of a copolyester polymer is laminated on one surface or both surfaces of a base layer made of aliphatic polycarbonate. When coextruding aliphatic polycarbonate and copolyester polymer, two layers adhere well to each other and are hardly delaminated from each other even without an adhesive and a tie layer, oxygen barrier property and low-temperature heat seal property can be provided as compared with a case where the copolyester polymer alone is used, the cost can be reduced because a separate adhesive or a tie layer is not required, and the manufacturing cost can be significantly reduced because the constitution of layers is simplified.

Multilayer film

Provided are a composition for preparing expandable polypropylene carbonate and an expandable polypropylene carbonate prepared therefrom, and more particularly, to a composition for preparing expandable polypropylene carbonate capable of using supercritical carbon dioxide as a foaming agent and producing a foam having excellent moldability by using an appropriate foaming method. By using the composition according to the present invention, highly magnificated expandable polypropylene carbonate capable of having excellent thermal stability and dimensional stability can be prepared.
