阅读说明：本技术 具有高硫含量的弹性体三元共聚物及其制备方法 (Elastomeric terpolymers having high sulfur content and method of making same ) 是由 阿尔贝托·雷纳托·德·安吉利斯 乔瓦尼·瑞格蒂 恰拉·弗朗西斯卡·卡罗扎 于 2019-05-10 设计创作，主要内容包括：具有高硫含量的弹性体三元共聚物包含：-相对于所述弹性体三元共聚物的总重量高于或等于40重量％、优选在55重量％至90重量％的范围内的量的硫；-第一单体,其选自芳族乙烯基化合物,优选选自苯乙烯、二乙烯基苯、乙烯基甲苯、叔丁基苯乙烯、ρ-甲基苯乙烯、γ-甲基苯乙烯、α-甲基苯乙烯、乙烯基萘；-第二单体,其选自：-芳族乙烯基化合物,优选选自苯乙烯、二乙烯基苯、乙烯基甲苯、叔丁基苯乙烯、ρ-甲基苯乙烯、γ-甲基苯乙烯、α-甲基苯乙烯、乙烯基萘；-具有通式(I)的单体：CH_2＝CH-(CH_2)_y-(X)_n-(X)_m-(CH_2)_x-CH＝CH_2,其中：-X表示硫原子、硒原子、碲原子,优选硫原子、硒原子；-y和x彼此相同或不同,是在0至4的范围内的整数；-n和m彼此相同或不同,是在0至3的范围内的整数,n和m中的至少一个等于1；所述第一单体和所述第二单体以相对于所述弹性体三元共聚物的总重量低于或等于60重量％、优选在10重量％至45重量％的范围内的量存在；所述第一单体和所述第二单体彼此不同。所述具有高硫含量的弹性体三元共聚物可以有利地用于许多应用,诸如例如隔热、传送带、传动带、柔性软管并且特别是轮胎用弹性体组合物。(Elastomeric terpolymers having a high sulfur content comprise: -sulfur in an amount higher than or equal to 40% by weight, preferably in the range from 55% to 90% by weight, relative to the total weight of the elastomeric terpolymer; -a first monomer selected from aromatic vinyl compounds, preferably from styrene, divinylbenzene, vinyltoluene, tert-butylstyrene, p-methylstyrene, gamma-methylstyrene, alpha-methylstyrene, vinylnaphthalene; -a second monomer selected from: aromatic vinyl compounds, preferably selected from styrene, divinylPhenyl benzene, vinyl toluene, tert-butyl styrene, rho-methyl styrene, gamma-methyl styrene, alpha-methyl styrene, vinyl naphthalene; -monomers having general formula (I): CH (CH) 2 ＝CH‑(CH 2 ) y ‑(X) n ‑(X) m ‑(CH 2 ) x ‑CH＝CH 2 Wherein: -X represents a sulfur atom, a selenium atom, a tellurium atom, preferably a sulfur atom, a selenium atom; -y and x, equal to or different from each other, are integers ranging from 0 to 4; -n and m, equal to or different from each other, are integers ranging from 0 to 3, at least one of n and m being equal to 1; the first monomer and the second monomer are present in an amount lower than or equal to 60% by weight, preferably in the range from 10% to 45% by weight, relative to the total weight of the elastomeric terpolymer; the first monomer and the second monomer are different from each other. The elastomeric terpolymers having a high sulfur content may be advantageously used in many applications such as, for example, elastomeric compositions for thermal insulation, conveyor belts, power transmission belts, flexible hoses and, in particular, tires.)
