    摘要： This invention relates to a p-methyl styrene polymer represented by the following formula: ##STR1## Z denotes a group such as a functional group. Poly p-methylstyrene (PPMS) is lithiated by reaction with n-butyllithium. The lithiated PPMS is used to prepare polymers containing functional groups. As an example, a solution of PPMS (MW 260,000), 1.0 g in 20 ml of cyclohexane, was reacted with n-butyllithium, 8.5 mmol, and tetramethylethylenediamine, 8.7 mmol, for 20 hours to obtain a precipitate. The precipitate was dissolved in THF, and CO.sub.2 was blown into the solution. The solution was washed with an aqueous solution of HCl and dropped into methanol to obtain a solid polymer having carboxyl group functionality.

    摘要： A novel styrene copolymer having a functional group, i.e. silyl group on the para-position of the aromatic ring, useful as a functional polymer, is provided. An effective process for the production thereof comprises contacting a random or block copolymer of p-methylstyrene and .alpha.-methylstyrene with an organolithium compound to lithiate partly the p-methyl group in the copolymer and then reacting the lithiated copolymer with a silicon compound represented by the general formula (R.sup.1)(R.sup.2)(R.sup.3)SiX wherein R.sup.1, R.sup.2 and R.sup.3 are, same or different, alkyl groups with 1 to 6 carbon atoms or alkenyl groups with 2 to 6 carbon atoms, at least one of R.sup.1, R.sup.2 and R.sup.3 being an alkenyl group, and X is a halogen atom.
