A polymer comprising recurring units of a sulfonium salt represented by formula (1) is provided as well as a chemically amplified resist composition comprising the same. R¹ is H, F, methyl or trifluoromethyl, R² to R⁴ are C₁-C₁₀ alkyl or alkoxy, R⁵ is C₁-C₃₀ alkyl or C₆-C₁₄ aryl, k, m and n are 0 to 3. The recurring units generate a sulfonic acid upon exposure to high-energy radiation so as to facilitate effective scission of acid labile groups in the resist composition. The resist composition exhibits excellent resolution and a pattern finish with minimal LER.

A positive resist composition comprises a polymer comprising recurring units having a sulfonium salt incorporated therein as a base resin which becomes soluble in alkaline developer under the action of acid. The polymer generates a strong sulfonic acid upon exposure to high-energy radiation so as to facilitate effective scission of acid labile groups in the resist composition.

A drying shrinkage-reducing agent which comprises a polymer containing as an essential component at least one structural unit (I) represented by the following formula (1):

wherein R¹, R², and R³ independently stand for a hydrogen atom, a methyl group, or a —(CH₂)_pCOOX group, wherein X stands for a hydrogen atom, a monovalent metal, a divalent metal, an ammonium group, an organic amine group, or a hydrocarbon group, and p is an integer of 0-2; and R⁴ stands for a hydrocarbon group of 4-30 carbon atoms,

and exhibiting surface tension in the range of 25-50 mN/m in a solution containing 0.2 mass % of the polymer in a cement supernatant is provided. The drying shrinkage-reducing agent manifests no dispersibility in an amount capable of attaining necessary drying shrinking-reducing properties and, when used in combination with a dispersing agent, acquires ability to adjust the dispersibility and the drying shrinkage-reducing properties fit for the purpose.

A polymer of which dissolution rate in an alkaline developer increases under the action of acid comprises recurring units having formulae (1) and (2) wherein R¹, R², and R⁴ are H or methyl, R³ is difluoromethyl or trifluoromethyl, and X is tertiary alkyl.
