Abstract: A polypropylene-based adhesive containing a polypropylene-based resin (A′) prepared by reducing the weight-average molecular weight of a polypropylene-based resin (A) by decomposition, in which the melting endotherm (ΔH-D) of the polypropylene-based resin (A) is 0 J/g or more and 80 J/g or less, as obtained from a melting endothermic curve drawn by holding a sample at −10° C. for 5 minutes in a nitrogen atmosphere followed by heating it at 10° C./min using a differential scanning calorimeter (DSC).

Abstract: A transition metal compound from Periodic Table Group 3 to 10 or lanthanide, of formula (I): In formula (I), A1 and A2 are independently a crosslinker of formula (II) X is a σ or π-bonding ligand, and plural Xs may differ; Y is a Lewis base, and plural Ys may differ and/or crosslink with Y or X; q is an integer from 1 to 5, representing [(valence of M)−2]; r is an integer from 0 to 3; M is a metal from Group 3 to 10 or a lanthanide; n and m are independently an integer from 0 to 4; and plural Rs may differ. In formula (II), E is C, Si, Ge, or Sn; R1 and R2 are independently a H, a halogen, or a C1 to C20 hydrocarbon, optionally halogenated, and may bond together to form a ring, and e is an integer from 1 to 4.

Abstract: Disclosed is a method for producing an unsaturated hydrocarbon compound wherein an α-olefin is dimerized by using a catalyst system composed of a metallocene compound (A) and an oxygen-containing organometallic compound modified with a halogen-containing compound (B). By this method, an unsaturated hydrocarbon compound having unsaturated double bonds in a high ratio, in particular the one having a terminal vinylidene group can be produced efficiently.
