<p>The present invention provides a granular stabilizer for a polymer which is low-dusting and thus is easy to be handled. The present invention relates to a granular stabilizer for a polymer, comprising a compound shown by the formula (1): wherein R1sand R2s each independently represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, or a cycloalkyl group having 5 to 8 carbon atoms;R3s each independently represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; and X represents a single bond, a sulfur atom, an oxygen atom, an alkylidene group having 1 to 8 carbon atoms or a cycloalkylidene group having 5 to 8 carbon atoms.</p> |
