Abstract
PURPOSE: To prepare a highly stable oxymethylene copolymer composition, by adding a nitrogen-containing polymer, a hindered phenol, and cyanoguanidine as stabilizers, to an oxymethylene copolymer obtained by adding a tri-valent organo-phosphorus compound to the polymerization system prepared by the polymerization reaction using a boren fluoride-type polymerization catalyst.
CONSTITUTION: Oxymethylene is polymerized in the presence of a boron fluoride- type polymerization catalyst such as boron fluoride, hydride of boron fluoride, etc. The polymerization is terminated by adding a tri-valent organo-phosphorus compound such as ethyl tetramethylene phosphine, triethyl phosphine, etc. The oxymethylene copolymer thus obtained is compounded with stabilizers comprising (a) a nitrogen-containing polymer having groups of formula I and II (R4 is H, alkyl, aryl, etc.), (b) a hindered phenol of formula III (R5W7 are alkyl, aryl, etc.), and (c) cyanoguanidine.
