Abstract

PURPOSE:To obtain a silylated styrene polymer having excellent heat resistance, good solubility in an organic solvent and crosslinkability with light or electron beams, by bonding three specified kinds of repeating units at random. CONSTITUTION:A high-silicon photosensitive styrene polymer is obtained by bonding repeating units of formulas I, II and III at random. In the formulas, R<1>, R<2> and R<3> are each a 1-6C alkyl, R<4>, R<5> and R<6> are each a 1-6C alkyl, a 2-6C alkenyl and at least one of them is an alkenyl, and the molar ratio of formula I/formula II/formula III is 1-70/1-60/1-40. This polymer can be obtained by lithiating poly(p-methylstyrene) and introducing this (trialkylsilyl)silyl and alkenyl-silyl groups thereinto. This polymer has excellent heat resistance, good solubility in an organic solvent and crosslinkability with light, electron beams or the like, and can be applied to various functional polymeric materials such as photo-curable coatings requiring heat resistance, electron beam-curable coatings and photopolymers for printing plates.

The reaction temperature can be freely set from -70°C to the boiling point of each solvent, but in order to efficiently achieve a high lithiation rate, a temperature above room temperature is desirable. Also, the organic lithiated polyester can be set arbitrarily.
The lithiation rate can be arbitrarily adjusted within the range of 50 unit moles or less. The amines may be used in an equivalent amount to the organolithium compound, but may be used in an excess amount.゛The reaction time varies depending on the reaction temperature, but it is usually α1 to 100 hours.By lengthening the reaction time, the lithium can be increased. Since polyPMS has high reactivity and reacts with moisture in the air, it is desirable to use it in the subsequent reaction without separating it.
