Procedure

Using azoisobutyronitrile as a polymerization initiator and t-dodecylmercaptan as a chain transfer agent, a t-butyl methacrylate, methyl methacrylate and methacrylic acid were polymerized to obtain a copolymer having a t-butyl methacrylate/methyl methacrylate/methacrylic acid compositional ratio of 40/50/10 and an Mw of 25,000. This copolymer is designated as acid-cleavable additive C1.
