Poly(dimethylsiloxane-co-methylphenylsiloxane) Usage And Synthesis

Chemical Properties

Poly(dimethylsiloxane-co-methylphenylsiloxane), also known as PDMS-MPS, is a high-performance and versatile polymer with exceptional stability, reliability, and durability. With a viscosity of 50cSt, it is finely balanced for optimal performance across various industrial and research applications. This compound has a unique molecular structure denoted as [Si(CH3)2O]x[Si(CH3)(C6H5)O]y. This particular composition derives from the meticulous combination of dimethylsiloxane and methylphenylsiloxane, imparting the compound with its distinctive properties.

Uses

Silicone oil has been used as a medium component in containerless protein crystallization techniques which do not require contact with a solid surface. It was used as an oil bath during the synthesis of methyl 2-methylazulene-1-carboxylate.

General Description

Silicone oil AP 150 Wacker is a conventional electrorheologic (ER) fluid. It was employed as an insulating medium during the poling of hard ferroelectric ceramics. Silicon oil is composed of a mixture of hydrophobic polymeric and monomeric compounds, containing silicon-oxygen bonds. Its physical and chemical characteristics have been reported. The utility of silicon oil as a vitreous substitute has been studied.
