    摘要： This invention relates to a p-methyl styrene polymer represented by the following formula:
    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 2 was blown into the solution. The solution was washed with an aqueous solution of HCI 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 α-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 1 ) (R 2 ) (R 3 ) SiX wherein R 1 , R 2 and R 3 are the 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 1 , R 2 and R 3 being an alkenyl group, and X is a halogen atom.

    摘要： Poly(p-methylstyrene)s having improved properties, in particular, higher heat resistance, are provided which have an isotactic pentad fraction of at least 700/0. The poly(p-methylstyrene)s can be prepared by polymerizing p-methylstyrene in the presence of a catalyst consiting of an activated titanium trichloride composition of titanium trichloride-aluminum halide compound-ether and a trialkylaluminum.
