| abstract | The present invention is an ethylene-α-olefin-non-conjugated polyene copolymer rubber composed of ethylene, α-olefin having 3 to 20 carbon atoms, and nonconjugated polyene,n n n (i) Intrinsic viscosity [η] measured in 135 degreeC decalin solvent is 1.5-5.0 dl / g,n n n (ii) the gη * value or the g 'value (wherein the gη * value is an intrinsic viscosity [η] measured in the above (i) and an ethylene-α-olefin non-conjugated polyene copolymer having this intrinsic viscosity [η]) The ratio of intrinsic viscosity [η] blank measured in a decalin solvent at 135 ° C. of a 70 mol% linear ethylene-propylene copolymer having an ethylene content of the same weight average molecular weight (by light scattering method) as that of rubber ([η] / [ η] blank ), and the g 'value is the intrinsic viscosity [η] measured in the above (i) and gel permeation chromatography (140 ° C., o-dichloro) of this ethylene-α-olefin-non-conjugated polyene copolymer. Ethylene content, determined by measuring benzene solvent), is defined as the ratio of the intrinsic viscosity [η] blank '(g' = [η] / [η] blank ') of 70 mol% linear ethylene-propylene copolymer conversion. .) Is between 0.6 and 0.9,n n n (iii) Mw / Mn is 3.0-50,n n n (iv) the iodine number is 10-40,n n n (v) the molar ratio of ethylene and α-olefin having 3 to 20 carbon atoms is 40/60 to 95/5,n n n (vi) The ethylene-α-olefin-non-conjugated polyene copolymer rubber, wherein the intensity ratio D (Tαβ / Tαα) of Tαβ to Tαα in the 13 C-NMR spectrum is 0.5 or less, and the copolymer rubber It relates to a rubber composition for sealing, a rubber molded body for sealing and a method for producing the molded body.n n n Ethylene-α-olefin-non-conjugated polyene copolymer rubber, rubber composition for sealing, rubber molded body for sealing |
