A polymer comprising recurring units derived from a polymerizable monomer having two structures of hydroxyphenyl methacrylate having a hydroxy group substituted with an acid labile group is used as base resin in a positive resist composition, especially chemically amplified positive resist composition. The resist composition forms a resist film which is processed by lithography into a pattern of good profile having a high resolution, minimal edge roughness, and etch resistance.
