Repeat Unit

–[CH₂–CH=CH–CH₂]ₓ–[CH₂–CH(C₆H₅)]ᵧ–[CH₂–CH(CN)]𝑧–

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

Two-phase system: rigid SAN matrix with dispersed polybutadiene rubber; balanced toughness, rigidity and processability; poor UV resistance.

Applications

LEGO bricks, automotive interior trim, 3D printing, appliance housings.
