white to light yellow crystal powde | [Uses]
p-Xylylene dichloride is a monomer used in preparation of poly(p-phenylene vinylene(PPV) nanotubes and nanorods by chemical vapor deposition (CVD) polymerization method. It was used in a study to investigate the effect of CVD monomer selection and reaction conditions on the resulting PPV polymer layer composition and luminescence properties. | [Uses]
α,α′-Dichloro-p-xylene is a monomer used in preparation of poly(p-phenylene vinylene(PPV) nanotubes and nanorods by chemical vapor deposition (CVD) polymerization method 1 . α,α′-Dichloro-p-xylene was used in a study to investigate the effect of CVD monomer selection and reaction conditions on the resulting PPV polymer layer composition and luminescence properties 2 . | [General Description]
α,α′-Dichloro-p-xylene undergoes phase transfer catalysed polycondensation with t-butylcyanoacetate to form carbon-carbon chain polymer. | [Flammability and Explosibility]
Notclassified | [Purification Methods]
