  • Patent number: 5629365
    Abstract: Aqueous latices adapted to forming visible light transparent, coherent polymeric films, e.g. in laminates, as protective coatings or as adhesives, comprising colloidal particles of a UV-absorbing polymer less than 5 micrometers in diameter. Useful UV-absorbing polymer include homopolymers and copolymers of vinyl-functionalized monomer of benzotriazole or benzophenone and mixtures with plasticizer and/or coalescing agent. Plasticizer and coalescing agents are useful for providing polymer with reduced glass transition temperature to facilitate coalescence of polymer particles into coherent films. Useful additives for the latices of this invention include wetting agents, surfactants, and crosslinking agents, anti-oxidants and radical scavengers. The latices of this invention are particularly useful in providing clear, thin coatings on windows, tags, labels, flooring, tents, awnings, containers and other UV-susceptible substrates.

  • Patent number: 5559175
    Abstract: Preparation of polyvinyl acetals which can form emulsifier- and surfactant-free aqueous dispersions and redispersible dry powders and contain copolymeric polyvinyl acetals with, in amounts sufficient to form a dispersion, comonomer units carrying sulfo salt groups which are derived from copolymeric polyvinyl alcohol (PVALs) which contained comonomer units carrying sulfonate groups in the salt form. The preparation is carried out by acetalization of the starting polyvinyl alcohols to be used with aldehydes or aldehyde acetals under acid-catalyzed acetalization conditions in an aqueous medium, emulsifier-free stable aqueous polyvinyl acetal dispersions being obtained, from which dry redispersible polyvinyl acetal powders can be obtained by spray drying or freeze drying. The polyvinyl acetals according to the invention can be plasticized by mixing in plasticizers both in their aqueous dispersion form and in the dry powder form.
