Abstract

PURPOSE: To produce the titled polymer having excellent lubricating properties and antistatic properties, by copolymerizing trioxane, HCHO or polyoxymethylene and a cyclic ether in the presence of a specified molecular weight modifier.
CONSTITUTION: 100pts.wt. Trioxane, HCHO or polyoxymethylene and a cyclic ether of formula III or IV [wherein R0 is H, (substd.) alkyl, (substd.) aryl] are copolymerized in the presence of a molecular weight modifier selected from alcohol- or carboxylic acid - alkylene oxide adducts of formula I or II [wherein R1, R3 are each H, (substd.) alkyl, (substd.) aryl; R2 is (substd.) alkyl, (substd.) aryl; m is 2W6; n is 1W1,000] to produce a polyacetal copolymer which has a number-average MW (except end groups) of 10,000W500,000 and in which at least one terminal of a linear polymer is blocked by the alcohol- or carboxylic acid - alkylene oxide adduct, said linear polymer having a structure where an oxyalkylene unit is inserted into a polymer composed mainly of repeating oxymethylene units.
