ABSTRACT:
An oxymethylene polymer of improved melt processability is provided by the addition of about 0.1-5 percent by weight of a low molecular weight copolyether-ester resin. The copolyether-ester consists essentially of long-chain ester units derived from long-chain glycols and dicarboxylic acids and short-chain ester units derived from low molecular weight diols and dicarboxylic acids.
