| titleOfInvention | Method for producing olefin resin |
| abstract | In the presence of a polymerization catalyst comprising a group 4 transition metal compound [A] containing a ligand having a dimethylsilylbisindenyl skeleton and a bridged metallocene compound [B] having a specific structure, In the reactor, ethylene and at least one α-olefin selected from α-olefins having 3 to 12 carbon atoms are copolymerized to produce an olefin resin satisfying the following requirements (I) to (IV): A method for producing an olefin resin. (I) Graft type olefin polymer [R1] comprised from a principal chain and a side chain is included. (II) The proportion of repeating units derived from ethylene is in the range of 50 to 90 mol% with respect to all repeating units, and the repeating is derived from at least one α-olefin selected from α-olefins having 3 to 12 carbon atoms. The ratio of the unit is in the range of 10 to 50 mol% with respect to all repeating units (however, the total of repeating units derived from ethylene and repeating units derived from α-olefins having 3 to 12 carbon atoms is 100 mol%). is there. (III) Melting | fusing point (Tm) measured by the differential scanning calorimetry (DSC) exists in the range of 0-100 degreeC. (IV) The intrinsic viscosity [η] measured in decalin at 135 ° C. is in the range of 0.1 to 10 dl / g. [Effect] According to the present invention, an olefin resin containing a graft type olefin polymer which is an ethylene / α-olefin copolymer having an amorphous side chain can be directly converted from a monomer into a single reactor in a single polymerization step. It can be manufactured and can be manufactured easily. [Selection figure] None |
