ABSTRACT:
There are disclosed a styrenic copolymer which comprises at least one structural unit represented by the general formula (I) ##STR1## and a structural unit represented by the general formula (II) ##STR2## or a structural unit represented by the general formula (IX) ##STR3## wherein the symbols are each as previously defined in the specification, the structural unit (II) or (IX) being contained in an amount of 0.01 to 99.9 mol %; and a process for the production of the above copolymer.
The above styrenic copolymer has a high degree of syndiotactic configuration in the stereoregularity of the main chain of the structural unit (I) as well as adhesivity and compatibility with a resin of a different type.
