    Abstract: 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. C.

    Abstract: Secondary products formed in the chlorination of butadiene can be reacted with phenols in the absence of iron catalysts to form novolak-like phenolic resins in such a way that the tetrachlorobutane present in the secondary products does not react. It can be distilled off with the excess phenol and isolated in pure form from the distillate obtained.

  • Patent number: 4889912
    Abstract: Acetylene terminated aspartimides are prepared using two methods. In the first, an amino-substituted aromatic acetylene is reacted with an aromatic bismaleimide in a solvent of glacial acetic acid and/or m-c=resol. In the second method, an aromatic diamine is reacted with an ethynyl containing maleimide, such as N-(3-ethynylphenyl) maleimide, in a solvent of glacial acetic acid and/or m-cresol. In addition, acetylene terminated aspartimides are blended with various acetylene terminated oligomers and polymers to yield composite materials exhibiting improved mechanical properties.
