Abstract
A polymer including a repeating unit derived from a monomer (1) represented by formula (1-1) (i.e., Ra—X—CY3-αZα) or formula (1-2) (i.e., Ra—X—NY2-βZβ), and having a tackiness of 800 gf or less, where Ra is a polymerizable organic group, X is a single bond or a divalent group, Y is each independently a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, α is an integer of 1 to 3, β is an integer of 1 or 2, and Z is each independently —Z1—SiZ23-mZ3m (where Z1, Z2, m, and Z3 are each as defined in the specification).
