Polymers having reactive functional groups at terminus and curable compositions comprising the same

摘要

A vinyl polymer having at least one group of the general formula (1) per molecule at the molecular chain terminus. -Z-R-CR¹-CR²R³ ( 1 ) wherein Z represents an oxygen atom, a sulfur atom, a group of the formula NR', R' represents a univalent hydrocarbon group containing 1 to 20 carbon atoms, or a bivalent organic group containing 1 to 20 carbon atoms, and R represents a carbonyl group, a direct bond or a bivalent organic group containing 1 to 20 carbon atoms; R¹ and R² are the same or different and each represents a hydrogen atom or a univalent organic group containing 1 to 20 carbon atoms, and R³ represents an organic group containing 1 to 20 carbon atoms; and a curable composition comprising the above vinyl polymer are provided.
