  • Organo-modified layered double hydroxides and composite polymer materials comprising same
    Patent number: 10745536
    Abstract: Layered double hydroxides organo-modified by 3-(4-hydroxyphenyl)propionic acid (HPPA), by 2-(4-hydroxyphenyl)ethylsulfonic acid or by a hydroxyphenylpropenoic acid, and to composite polymer materials having same. The composite materials are advantageously made of biosourced polymers such as poly(butylene succinate). These composite materials have improved properties over the polymers that make up the composition thereof, and over the composites of the prior art.
    Type: Grant
    Filed: May 19, 2016
    Date of Patent: August 18, 2020

  • Method for preparing poly(cyclohexane-1,4-dicarboxylate)s from cyclohexane-1,4-dicarboxylic acid, and composition
    Patent number: 6828410
    Abstract: Poly(1,4-cyclohexanedicarboxylate)s, especially poly(1,4-cyclohexanedimethylene-1,4-cyclohexanedicarboxylate), are prepared from at least one relatively non-volatile diol, such as 1,4-cyclohexanedimethanol, and cyclohexane-1,4-dicarboxylic acid by an esterification process in the presence of a catalyst, at a maximum temperature of about 260°. In one embodiment the procedure employs a two-step process, the second of which may be performed in the melt or in the solid state. A volatile diol such as ethylene glycol may also be present.
