The present invention is a polyolefin polymer containing vinyl groups at both ends thereof, and a composition and a molded product containing the polymer, wherein the polymer contains a constitutional unit derived from at least one selected from the group consisting of ethylene (a), an α-olefin (b) having 3 to 20 carbon atoms, and a cyclic olefin (c), and
(1) a ratio of terminal vinylation is 70% or more relative to all of both ends of molecular chains, and
(2) an intrinsic viscosity [η] is in the range of 0.01 to 10 dl/g as measured in a decalin solution at 135° C.
The polymer of the present invention may be molded by a LIM molding, an injection molding, a transfer molding, a compression molding, and the like, and is excellent in acid resistance, gas permeation resistance, hydrolysis resistance, and dynamic fatigue resistance. From the polymer, a thermoplastic resin composition and a crosslinkable resin composition, and a crosslinked composition having excellent mechanical characteristics are obtained.
本发明涉及一种聚烯烃聚合物,其两端含有乙烯基团,以及包含该聚合物的组合物和成型产品。该聚合物包含至少一种选自乙烯(a)、具有3至20个碳原子的α-烯烃(b)和环状烯烃(c)的构成单元,且(1)末端乙烯化比率相对于分子链的两端总量为70%或更高,(2)在135℃的癸酚溶液中测量的固有粘度[η]范围为0.01至10 dl/g。该聚合物可以通过LIM成型、注塑成型、转移成型、压缩成型等方法成型,并具有优异的耐酸性、气体渗透阻力、水解阻力和动态疲劳阻力。从该聚合物中可以得到热塑性树脂组合物和可交联树脂组合物,以及具有优异机械特性的交联组合物。
