Abstract
Acetal copolymers of trioxane and 1,3-dioxep-5-ene having a high degree of crystallinity and specific mole percent incorporations of 1,3-dioxep-5-ene are synthesized. The invention also provides a process for producing highly crystalline acetal copolymers by copolymerizing triozane and 1,3-dioxep-5-ene and precipitating the copolymer product from solution. The copolymers show much improved stability against halogen degradation.
Claims3
