Tertiary Copolymer [Effects of the Invention] In recent years, the development of substitute compounds for fluorocarbons, which cause ozone layer destruction, has been actively conducted, and dimethyl ether is attracting attention as a candidate for a fluorocarbon substitute. Conventionally, when dimethyl ether is used in aerosol products, there has been a high incidence of gas leakage from each aerosol product during storage, and there has been a strong desire to develop a sealing material for use in the seal portion.

This problem can be solved by using PDM and nylon.
