Abstract

The invention discloses integrated functionalized itaconate / butadiene / isoprene bio-based rubber and vulcanized rubber and a preparation method thereof, and relates to the technical field of rubber synthesis, the number-average molecular weight of the bio-based rubber is 50,000-1,000,000, preferably 100,000-8,000; the molecular weight distribution is 1.5 to 10.0, preferably 2.0 to 5.0. The high-performance bio-based rubber is prepared through copolymerization of the itaconate monomer, the butadiene monomer, the isoprene monomer and the functionalized monomer, the wet skid resistance of the material is obviously improved, meanwhile, rolling resistance is not lost, an effective thought is provided for preparation of green tires, and excellent comprehensive performance is shown in the aspect of tire application. Through reasonable structural design, the comprehensive performance of the integrated functionalized itaconate / butadiene / isoprene bio-based rubber can be compared with that of functionalized solution polymerized styrene-butadiene rubber (SSBR), and the bio-based integrated rubber is not reported before.
