  • Patent number: 4724267
    Abstract: Bis(haloacylaromatic) compounds have been made by a new process in which monohaloacylated aromatic compounds have been reacted by a coupling reaction. These bis(haloacylaromatic) compounds can be employed as monomers in the preparation of polyesters and polyamides which have easy processability. The monohaloacylated compound is coupled by reacting two moles of the monomer with a carbon or sulfur compound containing at least two halogen atoms in the presence of a Friedel-Crafts catalyst.

  • Patent number: 4707558
    Abstract: Monomers and oligomers containing a plurality of vinylbenzyl ether groups are prepared by reacting a material containing a plurality of aromatic hydroxyl groups such as tetramethyltetrabromobisphenol A with a vinylbenzyl halide such as vinylbenzyl chloride in the presence of a polar aprotic solvent such as dimethylformamide. The monomers and oligomers prepared by this process have an improvement in one or more properties selected from dielectric constant (before and/or after moisture absorption) or thermal stability. Also disclosed are new monomers and oligomers containing a plurality of vinylbenzyl ether groups such as bis(vinylbenzyl)ether of dicyclopentadienyl bisdimethylphenol.
