abstract |
The present invention is concerned with a vinyl polymernhaving at least one group of the general formula (1) per moleculenat the molecular chain terminus.n -Z-R-CR 1 =CR 2 R 3 nwherein Z represents an oxygen atom, a sulfur atom, a group ofnthe formula NR', R' represents a univalent hydrocarbon groupncontaining 1 to 20 carbon atoms, or a bivalent organic groupncontaining 1 to 20 carbon atoms, and R represents a carbonylngroup, a direct bond or a bivalent organic group containing 1nto 20 carbon atoms; R 1 and R 2 are the same or different and eachnrepresents a hydrogen atom or a univalent organic groupncontaining 1 to 20 carbon atoms, and R 3 represents an organicngroup containing 1 to 20 carbon atoms. n The present invention is further concerned with a curablencomposition comprising the above vinyl polymer. |
