THIETANE COMPOUND, POLYMERIZABLE COMPOSITION COMPRISING THE COMPOUND, AND USE OF THE COMPOSITION

摘要

Disclosed is a thietane compound represented by the general formula (1) [wherein M represents an element belonging to Group 14 on the super long format of the periodic table; X<SUB>1</SUB>'s independently represent a sulfur or oxygen atom; p represents an integer ranging from 2 to (n-1) (inclusive); and n represents the number of valency of the metal atom M, provided that: when n-p is 1, then R<SUB>2</SUB> represents a linear or branched alkyl group having 1 to 3 carbon atoms which may have a substituent; and when n-p is 2 or greater, then multiple R<SUB>2</SUB>'s independently represent a linear or branched alkyl group having 1 to 3 carbon atoms which may have a substituent or multiple R<SUB>2</SUB>'s may together form a ring containing M in which the alkyl chain forming the ring has 1 to 3 carbon atoms and the ring-constituting moiety has no sulfur atom].
