Repeat Unit
–[O–CO–C(CH₃)=CH₂]–R–[CH₂=C(CH₃)–CO–O]–
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
Epoxy backbone with reactive end groups only — fewer ester links than UP means far better hydrolytic and chemical resistance at moderate cost.
Applications
Chemical storage tanks, pipe linings, marine laminates, rebar.
