Repeat Unit
–[CH₂–CH(CONH₂)]ₙ–
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
Water-soluble; crosslinked gels have precisely controllable mesh size; the monomer is a neurotoxin although the polymer itself is not.
Applications
SDS-PAGE electrophoresis gels, water-treatment flocculant, enhanced oil recovery.
