Abstract
A functional polymer of styrene derivative a copolymer of a monomer A having the structure represented by the formula (I) and a comonomer. The functional polymer of styrene derivative of the present invention can be easily further chemically modified. Meanwhile, basic properties of the functional polymer, such as glass transition temperature, viscoelasticity and the like, can be easily adjusted by adjusting the amount of the styrene derivative added.
