摘要:
Iodoisocyano, iodourea and oxazole modified 1,3 dioxep-5-ene ring monomers are synthesized and used in copolymerization reactions with trioxane to produce acetal copolymers with backbone functional groups. The invention also concerns processes for the production of acetal copolymers containing iodourea and oxazole functional groups from acetal copolymers with backbone double bonds.
