METHOD FOR PRODUCTION OF POLYACETALS Russian patent published in 1995 - IPC

Abstract RU 2044000 C1

FIELD: production of polyacetals. SUBSTANCE: polyacetals are prepared by polymerization of trioxane with cyclic acetals in the medium of organic solvent, conversion of monomers being 30-70 mass During said process agent which controls molecular weight is added. Said agent is chosen of group which contains low molecular weight linear acetals with tail methoxyl groups. EFFECT: improves efficiency of the method. 1 tbl
