    Metal phthalocyanine intermediates for the preparation of polymers

    Get PDF
    Metal 4, 4', 4"",-tetracarboxylic phthalocyanines (MPTC) are prepared by reaction of trimellitic anhydride, a salt or hydroxide of the desired metal (or the metal in powdered form), urea and a catalyst. A purer form of MPTC is prepared than heretofore. These tetracarboxylic acids are then polymerized by heat to sheet polymers which have superior heat and oxidation resistance. The metal is preferably a divalent metal having an atomic radius close to 1.35A

    The quality factor in patent systems

    Get PDF
    In this paper, Bruegel senior Fellow Bruno van Pottelsberghe develops a methodology to compare the quality of examination services in different patent offices. Quality is defined as the extent to which patent offices comply with their patentability conditions in a transparent way. The methodology consists of a two-layer analytical framework encompassing 'legal standards' and their 'operational design', which includes several interdependent components that affect the stringency and transparency of the filtering process.
