Abstract: The object of the invention is to provide a novel olefin-based molded product useful for various applications. An olefin-based molded product comprising a polymer including a structural unit of at least one polar olefin monomer represented by the general formula (I) CH2=CH—R2—Z(R1)n is provided. In the formula, Z is a hetero atom selected from the group consisting of nitrogen, oxygen, phosphorus, sulfur, and selenium; R1 is a substituted or unsubstituted hydrocarbyl group having 1 to 30 carbon atoms; n is an integer of 1 or 2 depending on the atomic species of Z; and R2 is a substituted or unsubstituted hydrocarbylene group having 2 to 20 carbon atoms.

Abstract: An object of the present invention is to provide a novel method of producing a nonpolar olefin polymer (e.g., a copolymer of a nonpolar olefin and a polar olefin). The present invention provides a method of producing a polar olefin polymer or copolymer, the method including the polymerization step of polymerizing a polar olefin monomer using, as a catalyst, a polymerization catalyst composition containing: 1) a metallocene complex represented by Formula (I), which contains a central metal M that is scandium (Sc) or yttrium (Y), a ligand Cp* containing a cyclopentadienyl derivative and being bound to the central metal, monoanionic ligands Q1 and Q2, and W neutral Lewis bases L wherein W is an integer of 0 to 3; and 2) an ionic compound composed of a non-coordinating anion and a cation.

Abstract: A liquid crystal display comprises a liquid crystal module (10) having a predetermined shape and having a back side covered with a metal back case (12); a liquid crystal drive circuit board (20) electrically connected at one side of the liquid crystal module (10), extending toward the central portion from the one side by predetermined length, having an electric connector (22) disposed on one side of the circuit board (20), and mounted on the metal back case (12); and a metal cover (30) having a cutout (33) large enough to expose the electric connector (22) and covering the circuit board (20). An earth terminal (36) is provided at one edge of the cutout (33) and is brought into elastic contact with an earth contact (24a) provided on one side of the circuit board (20) when the circuit board (20) is covered with the metal cover (30). With this constitution, a stable ground line is formed in the display by a simple machining to avoid noise interference.
