Abstract
PURPOSE: To prepare the titled polymer containing little oligomer by-product and having a molecular weight within a specific range, in high efficiency, by polymerizing parahydroxystyrene (PHS) in the presence of a specific organic carboxylic acid, ascorbic acid, and CO2.
CONSTITUTION: Crude PHS is, if necessary purified to some extent to reduce the content of impurities to about ≤80wt% based on the PHS, and polymerized pref. at 60W200°C for 10minW10hr under atmospheric or positive pressure in the presence of pref. 0.1W50wt%, based on the PHS, of a polymerization catalyst selected from (A) an organic carboxylic acid having a dissociation constant of pref. 10-9W10-4 at normal temperature (e.g. aliphatic saturated monocarboxylic acid such as acetic acid, aliphatic polycarboxyic acid such as succinic acid, etc.), (B) ascorbic acid, (C) carbonic acid and (D) CO2, if necessary, in the presence on an inert solvent and a molecular weight regulating agent (e.g. water, methanol, etc.).
EFFECT: Only the PHS can be selectively and completely polymerized.
USE: Functional polymer material.
