| abstract |
An object of the present invention is to provide a derivative of polybutadiene which is preferable as a material of a curable composition for obtaining a cured product having a high shear force. The present invention relates to compounds of formula (I) (Wherein R 1 , R 2 and R 3 each independently represent an unsubstituted or substituted aryl group, an alkyl group or an aralkyl group, provided that at least one of R 1 to R 3 is an aryl group or A silylated polybutadiene characterized by containing a repeating unit represented by the following formula (1): wherein R 1 represents a hydrogen atom or an alkyl group, to provide. |
