Methyl/Phenyl Polysilsesquioxane is a resinous material composed of a mixture of three-dimensional siloxane polymers and/or oligomers with cage structures.
Definition
Methyl/Phenyl Polysilsesquioxane is a resinous material composed of a mixture of three-dimensional siloxane polymers and/or oligomers with cage structures. For the oligomers, each silicon atom in the polysilsesquioxane is connected via oxygen atoms to three other silicon atoms and can be represented by the empirical formulation RSiO3/2, where R represents a mixture of methy and phenyl groups. For the larger polymeric polysilsesquioxanes, some of the silicon atoms are not connected to other silicon atoms and instead have a silanol (SiOH) group.

JCIA labelling name （メチル／フェニル）ポリシルセスキオキサン: 本品は、籠構造を有する三次元シリコーン化合物及び／又はオリゴマーの混合物からなる樹脂状化合物であり、オリゴマーは、ポリシルセスキオキサン内の各ケイ素原子が３つの他のケイ素原子に酸素原子を介して結合され、RSiO3/2の化学式によって表すことができる。より大きなポリシルセスキオキサン重合体の場合、ケイ素原子の一部は他のケイ素原子に結合されず、代わりにシラノール基 (SiOH)を有する。 R は メチル基及びフェニル基の混合物を表す。
