✦ Synopsis

Abstract

The porous copolymer films of N‐methacryloyl‐L‐alanine methyl ester and diethyleneglycol‐bis‐allylcarbonate (diallyl oxydiethylene dicarbonate) were hydrolyzed with 1 M NaOH solution for 40 min at 25°C. The pores of the films showed pH response in diameter. The pore diameter of 3,7 μm in the buffer solution of pH 3 was closed completely at pH 5.
