Abstract

PURPOSE:To easily obtain the titled compound in high purity and yield, without causing pollution with waste heavy metals, by using activated clay as a catalyst, carrying out addition reaction of a specific methacrylate with an alkylene oxide and separating the activated clay from the product using a simple operation such as filtration. CONSTITUTION:The objective compound of formula II (A2 is 2-4C alkylene; n is 1-20) useful as a fiber-modifying agent, flocculant, dispersant, etc., is produced by the addition reaction of (A) a methacrylate of formula I (R is H or CH3; A1 is A2) such as 2-hydroxyethyl methacrylate with (B) an alkylene oxide such as ethylene oxide in the presence of (C) activated clay produced by the acid treatment of a raw clay composed mainly of montmorillonite clay such as galeon earth. The addition reaction is carried out 20-90 deg.C for 1-20hr under normal pressure or positive pressure preferably in an inert gas atmosphere such as N2 gas. The recovered activated clay may be reutilized or discarded as it is.
