The invention relates to double-end functionalized solution polymerized styrene-butadiene rubber as well as a preparation method and application thereof. The general formula of the double-end functionalized solution polymerized styrene-butadiene rubber is A (SOL) mPB, wherein SOL is a structural unit from a divinyl compound and/or an aromatic vinyl compound, and m is 3-300; p is a copolymerization unit of butadiene and styrene; a is of a structure as shown in a formula (1); b is of a structure as shown in a formula (2); in formula (1), X is O or S. Two ends of a macromolecular chain of the solution polymerized styrene-butadiene rubber are respectively provided with an N, O (or S) atom-containing group and a siloxane group, and the N-containing group can interact with a group on the surface of carbon black to promote the dispersion of the carbon black; meanwhile, the siloxane group can effectively improve the affinity of the rubber and the white carbon black and promote the dispersion of the white carbon black. # imgabs0 #
本发明涉及双端官能化溶聚丁苯橡胶及其制备方法和应用。该双端官能化溶聚丁苯橡胶的通式为:A(SOL)mPB;其中,SOL为来自二乙烯基化合物和/或芳香族乙烯基化合物的结构单元,m为3‑300;P为丁二烯与苯乙烯的共聚单元;A为式(1)所示结构;B为式(2)所示结构;式(1)中,X为O或S。本发明的溶聚丁苯橡胶的大分子链两端分别带有含有N、O(或S)原子基团和硅氧烷基团,含N基团的存在可与炭黑表面的基团发生相互作用,促进炭黑分散;同时硅氧烷基团可有效改善橡胶与白炭黑的亲和性,促进白炭黑分散。#imgabs0#
