Abstract
The invention relates to a terpolymer of mono-ethylene arene, conjugated diene 1 and conjugated diene 2, preparation method thereof and application thereof. The obtained copolymer rubber has good anti-wet slipping performance and low rolling resistance. The terpolymer has greatly low rolling resistance and fine anti-wet slipping performance and the tan Delta is below 0.071 at 60 degree and the tan Delta is above 0.523 at 0 degree, wherein the ratio of the tan Delta at 0 degree to the tan Delta at 60 degree is above 7. The invention can be widely used in rubber articles field such as tyre.
Description
A kind of ternary copolymer rubber with low rolling resistance and high wet skid resistance, its preparation method and application field of invention The invention relates to a ternary copolymer rubber, in particular to a terpolymer of conjugated diene 1, conjugated diene 2 and monovinylarene and a preparation method thereof. The ternary copolymer rubber of the invention has low rolling resistance and good wet skid resistance, and can be widely used in the field of rubber products such as tires. Background technique Various common rubbers currently used, such as butadiene rubber (BR), natural rubber (NR), emulsion polystyrene butadiene rubber (ESBR), solution polymerization styrene butadiene rubber (SSBR), etc., have their own unique advantages, but There are also shortcomings. For example, BR has the best flexibility, low rolling resistance, but poor wet skid resistance. NR is moderately flexible and has good rolling resistance, but average wet skid resistance. Styren...
