Cytec Granted Chinese Patent for PTZ Phenothiazine Prill

Published on 2007-09-07. Author : SpecialChem

West Paterson -- Cytec Industries Inc. announced the allowance of its patent covering PTZ® phenothiazine prill by the Chinese Patent & Trademark Office. The patent should grant shortly. "Prill" is the spherical bead form of phenothiazine.

Cytec is a leading producer of phenothiazine, which is an acrylic stabilizer, used in the production of acrylic acids, acrylic esters, and methyl methacrylate monomer. End use applications include super absorbent polymers, coatings, inks and packaging, in addition to acrylic sheets. Prill is the product form preferred by most manufacturers because it creates less dust and is easier to handle than powder and flake forms. Cytec has manufactured PTZ prill since December, 2000 at its facility in Mt. Pleasant, Tennessee.

China joins seven other countries in recognizing Cytec's intellectual property related to PTZ phenothiazine prill. Patent applications are pending in all other countries where acrylic acids, esters, or methyl methacylate are produced. Contact Cytec for a complete list of patents.
