The present invention relates to a hydrocarbon resin production method comprising thermal polymerization under non-catalytic conditions, thereby enabling a narrow molecular weight distribution and the realization of uniform physical properties. Specifically, the present invention relates to a hydrocarbon resin production method and a hydrocarbon resin produced thereby, the method comprising thermal polymerization without a catalyst and an initiator, thereby enabling, by a low polydispersity index, a narrow molecular weight distribution, and thus a hydrocarbon resin having uniform physical properties.

The present invention relates to a high-melt-strength polypropylene resin, and a preparation method therefor. A method for preparing the high-melt-strength polypropylene resin, according to the present invention, comprises the steps of: creating a polypropylene by polymerizing propylene monomers in the presence of a metallocene catalyst; and putting a diene compound and a comonomer into the created polypropylene and unreacted propylene monomers and reacting same, thereby forming a C40 or greater long-chain branch on the main chain of the polypropylene.

This invention relates to a silane-functionalized resin composition having a polymer backbone, wherein the polymer backbone is selected from at least one of C.sub.5 homopolymers and copolymer resins, terpene homopolymer or copolymer resins, pinene homopolymer or copolymer resins, C.sub.9 homopolymers and copolymer resins, C.sub.5/C.sub.9 copolymer resins, alpha-methylstyrene homopolymer or copolymer resins, and combinations thereof, and wherein the polymer backbone is substantially free of styrene copolymer; and a silane, where the ratio of the mole percent of the silane to the mole percent of the polymer backbone in the composition is in the amount of 0.04 to 3.0 as determined by H-NMR.

A multi-block polyolefin copolymer (MBPC) is disclosed comprising: i) a combination of a semicrystalline polymer block and an amorphous polymer block, or ii) at least two amorphous polymer blocks, or iii) at least two semicrystalline polymer blocks. The semicrystalline polymer blocks A and C are independently derived from 1,3-butadiene monomer with 80 to 97 wt. % of 1,4 addition, based on weight of the polymerized 1,3-butadiene monomer in each block A and C. The amorphous polymer block B is derived from at least one monomer selected from isoprene monomer, 1,3-butadiene monomer with 21 to 85 wt. % incorporation by 1,2 addition, and mixtures thereof. The MBPC can be used as a compatibilizer for compatibilization of blends of two or more polyolefins different from each other. Such polyolefin blends provide improved mechanical properties and processability for producing various articles.
