    • PROBLEM TO BE SOLVED: To provide a new star polymer having stimulus responsiveness and antifouling property. SOLUTION: The star polymer includes a core part and three or more branch parts coupled to the core part. The core part is made of a crosslinked polymer of a dialkenyl compound. Part or all of the branch parts are monovalent organic groups having a number-average molecular weight of 1,000-1,000,000 represented by the formula (I f ): -(CH(-X-R 1 )-CH(-R 2 )) p -R f , wherein R 1 represents an unfluorinated monovalent organic group; R 2 represents H or alkyl; R f represents a fluorinated monovalent organic group; X represents a single bond, -O-, -S-, -NH- or -N(-CH 3 )-; and p represents an integer of ≥1. The remainders of the branch parts are monovalent organic groups having a number-average molecular weight of 1,000-1,000,000 represented by the formula (I o ): -(CH(-X-R 1 )-CH(-R 2 )) p -R o , wherein R o represents an unfluorinated monovalent organic group; and the other symbols represent the same meanings as the above symbols.
