Chemical Properties

white to light yellow crystal powde

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 .

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.

General Description

α,α′-Dichloro-p-xylene undergoes phase transfer catalysed polycondensation with t-butylcyanoacetate to form carbon-carbon chain polymer.

Flammability and Explosibility

Not classified

Purification Methods

Crystallise the xylene from *benzene and dry it under vacuum. [Beilstein 5 IV 967.]
