Repeat Unit
–[CH₂–CH(CH₂Cl)–O]ₓ–[CH₂–CH₂–O]ᵧ–
The repeating unit is the smallest structural fragment whose repetition builds the whole chain. Subscripts show the relative share of each unit in copolymers.
Key Properties
Combines good fuel resistance with low gas permeability and useful low-temperature flexibility.
Applications
Fuel hoses, vapour-emission control, air-conditioning hose.
