Abstract
A polyacetal suitable for moldings which are excellent in lubricity, wear and antistatic properties, which has at least one terminal of its linear polymer molecule capped with an alkylene oxide adduct of an alcohol or a carboxylic acid, which adduct is of the formula ##STR1## wherein R.sub.o is a hydrogen atom, alkyl group, substituted alkyl group, aryl group, or substituted aryl group, R.sub.o 's may be the same or different, R.sub.1 is an alkyl group, substituted alkyl group, aryl group, or substituted aryl group, R.sub.2 is a hydrogen atom, alkyl group, substituted alkyl group, aryl group, or substituted aryl group, m is from 2 to 6, and n is from 1 to 1,000; the number average molecular weight of said polyacetal being in the range from 10,000 to 500,000 excluding the terminal group.
