    摘要： The present inventors have obtained a PSQ derivative of a completely condensed type into which a functional group is readily introduced by using a novel PSQ derivative of an incompletely condensed type in which four alkaline metal atoms are bonded to silsesquioxane of a cage type having eight Si's. The above silsesquioxane derivative is represented by Formula (1). A silsesquioxane derivative to which alkaline metal atoms are bonded is represented by Formula (2). In Formula (1) and Formula (2), R is a group selected from alkyl, aryl and arylalkyl; Y is a group represented by Formula (a) or Formula (b); and M is a monovalent alkaline metal atom. X in Formula (a) and Formula (b) is hydrogen, halogen, a hydroxyl group or a monovalent organic group, and Z is —O—, —CH2— or a single bond. The preferred organic group is a functional group or a group having a functional group.

    摘要： A large part of conventional organic-inorganic composite materials is obtained by mechanical blending silsesquioxanes with organic polymers, and therefore it has been very difficult to control the structure thereof as the molecular aggregate of the composite materials. An object of the present invention is to provide a novel silicon compound having a living radical polymerization-initiating ability for an addition-polymerizable monomer and a polymer obtained using the same to thereby solve the problem described above regarding the conventional organic-inorganic composite materials. The present inventors have found that a novel silsesquioxane derivative to which a group having an ability to initiate polymerization of a monomer is useful as means for solving the problem described above. That is, the silsesquioxane derivative of the present invention is represented by Formula (1): wherein R1 is hydrogen, alkyl, aryl or arylalkyl; R2 and R3 are alkyl, phenyl or cyclohexyl; and A is a group having an ability to initiate polymerization of a monomer.
