Cyclolinear polyorganocarbosiloxanes were synthesized by the polyaddition reaction of dihydroorganocyclotetra(hexa,octa)siloxanes with divinylorganocyclotetra(hexa,octa)siloxanes in the presence of platinum catalysts. The effects of various forms of Pt colloids, which were obtained by reducing Pt complex compounds, on the structure and properties of the resulting polymers were studied by gel-permeation chromatog. and 29Si NMR spectroscopy. The phase transition temperatures were determined by DSC, X-ray diffraction anal., and optical microscopy. It was shown that a noncrystallizable polymer bearing decaethtylcyclohexasiloxane fragments is mesomorphic and forms a hexagonal 2D structure of the columnar type. In the experiment, the researchers used many compounds, for example, Dichlorodi(cyclopenta-1,3-dien-1-yl)platinate(II) (cas: 12083-92-0Reference of 12083-92-0).
Dichlorodi(cyclopenta-1,3-dien-1-yl)platinate(II) (cas: 12083-92-0) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Reference of 12083-92-0
