Patent number: 6344505Abstract: Provided is a composition which contains a mono- or bis-benzotriazole compound, an N-oxide thereof, or a mixture of at least two of the preceding compounds. Representative bis-benzotriazole compounds include 3,3′-bis-(2H-benzotriazol-2-yl)-5,5′-di-tert-octyl-1,1′-biphenyl-2,2′-diols. Representative mono-benzotriazole compounds include 3-(2H-benzotriazol-2-yl)-5,5′-di-tert-octyl-1,1′-biphenyl-2,2′-diols. These mono- and bis-benzotriazole compounds are useful as stabilizers of degradable polymers against the degradative action of ultraviolet light. Also provided is a method of making these benzotriazole compounds by oxidative dimerization of the corresponding monomeric benzotriazole or by reductive cyclization of the corresponding azo- compound.Type: GrantFiled: November 11, 1999Date of Patent: February 5, 2002Assignee: Cytec Industries Inc.Inventors: Donald H.

Patent number: 5770763Abstract: Novel difunctionalized cyclobutabenzene monomers of the general formula: ##STR1## wherein Z can be hydrogens or a cyclobutane ring; and X and Y are carboxyl, amino, alcohol, isocyanate, acid halide, or bis-acyl halide groups. Exemplary difunctional bitricyclodecatriene monomers are ?2,2'-bidicyclo?2.4.0!octa-1,3,5-triene!-5,5'-dicarboxylic acid (BXTA) and ?2,2'-bitricyclo?6.2.0.0!deca-1,3,(6),7-triene!-7,7'-dicarboxylic acid (QXTA). The difunctionalized bitricyclodecatriene monomers can form part of a polymer backbone chain in which the multiple butane ring functionalities can be easily opened to produce strong, three-dimensional covalent bond crosslinking between polymer chains. The crosslinking can be induced simply by heating the polymer to a temperature in excess of 250.degree.
