Abstract
AbstractA soluble hydrophilic polymer, poly[N‐(2,2‐dimethoxyethyl)methacrylamide] (4), and a crosslinked copolymer from N‐(2,2‐dimethoxyethyl)methacrylamide (3) and N,N′‐methylenediacrylamide (5) were prepared by radical polymerization in solution. Soluble hydrophilic poly[N‐(2,2‐dimethoxyethyl)‐N‐methacrylamide] (8) and the copolymer from N‐(2,2‐dimethoxyethyl)‐N‐methylacrylamide (7) and (5) were prepared by the same procedure. Acetal groups of these polymers can be hydrolyzed with HCl. N,N‐disubstituted methacrylamides, N(2‐formyl‐2‐methylpropyl)‐N‐methylmethacrylamide (2) and N‐(2,2‐dimethoxyethyl)‐N‐methylmethacrylamide (1) do not undergo radical homopolymerization.
