Abstract

PURPOSE: To obtain the titled polymer having improved lubricity and thermal stability, by using a specific compound containing an alkoxide group and/or a specific compound containing a carboxyl group as a molecular weight adjustor and terminating agent in preparing an acetal resin.
CONSTITUTION: Formaldehyde or trioxane is polymerized or a compound selected from the group consisting of the formaldehyde, trioxane and polyoxymethylene is copolymerized with a cyclic ether in the presence of a compound containing an alkoxide group of formula I (R1 is ≥8C alkyl, substituted alkyl or substituted aryl), e.g. lauryl alcohol, or a compound containing a carboxyl group of formula II (R1 is ≥7C alkyl, substituted alkyl or substituted aryl), e.g. stearic acid, alone or both as a molecular weight adjustor and terminating agent to give an acetal polymer having a number-average molecular weight of 10,000W500,000 and a friction coefficient of 0.20W0.30.
