Abstract

See full text

The present invention relates to the field of polymer materials. Disclosed are a random-syndiotactic block polybutadiene and preparation method thereof, the provided random-syndiotactic block polybutadiene having a structure of formula (I), and comprising a random polybutadiene structure and a syndiotactic 1, 2-polybutadiene structure, being useful as a compatibilizing agent to improve the compatibility of the syndiotactic 1, 2-polybutadiene/polybutadiene rubber blend. Experimental results show that, compared to a purely syndiotactic 1, 2-polybutadiene/polybutadiene rubber blend, the addition of the random-syndiotactic block polybutadiene thereto significantly improves the compatibility
