Hydrogels containing L-alanine ethyl esters as side chains show an int
rinsic temperature-responsive water absorption characteristic, which h
as been suppressed in the homopolymer by association of the terminal h
ydrophobic alkyl groups in the side chain, by introduction of comonome
r methacrylamide which serves as a spacer for disruption of the associ
ation of the side chains.
