General description

i-PMMA can be prepared from t-C4H9MgBr. Structure of crystalline isotactic poly(methyl methacrylate) (i-PMMA) was investigated by X-ray diffraction and infra red spectroscopic techniques.

Application

The polymeric blend of isotatic (i-) poly-(methyl methacrylate) & 6,13-bis(triisopropylsilylethynyl) pentacene can be used to prepare thin films transistors (TFTs).
