  • Process for the preparation of methyl p-vinylbenzoate and p-vinyl benzoic acid, and their use in latex compositions
    Publication number: 20020007010
    Abstract: The present invention describes a process for the direct preparation of methyl p-vinylbenzoate from methyl p-formylbenzoate using ketene in the presence of potassium acetate. The chief products obtained from the process are about a five to two ratio of methyl p-vinylbenzoate to p-carbomethoxycinnamic acid. The latter may be thermally decarboxylated, especially in the presence of copper powder, to produce additional quantities of methyl p-vinylbenzoate. Methyl p-vinylbenzoate may further undergo hydrolysis to form p-vinyl benzoic acid. Both methyl p-vinyl benzoate and p-vinyl benzoic acid may be polymerized with ethylenically unsaturated monomers to form useful latex compositions of the present invention.

  • Crosslinkers based on dibenzalacetone derivatives
    Patent number: 6194615
    Abstract: The present invention relates to the composition, process of preparation, and use of novel derivatives prepared from 1,5-bis-(4′-carbomethoxyphenyl)-1,4-pentadien-3-one. These novel compositions can act as crosslinkers with polyfunctional monomeric, oligomeric, and/or polymeric anhydrides, esters, carboxylic acids, isocyantes, epoxies, carbonates, acetoacetates, and alkoxylated melamines.
