  • Patent number: 5015708
    Abstract: What is described herein is a precipitation polymerization process and terpolymer products produced thereby. Polymerization is carried out in a reaction mixture of a vinyl lactam, e.g. vinyl pyrrolidone or vinyl caprolactam, a polymerizable carboxylic acid, e.g. acrylic acid or methacrylic acid, and a hydrophobic monomer, e.g. lauryl methacrylate, in a predetermined compositional range, in the presence of a polymerization initiator, and in an aliphatic hydrocarbon solvent, particularly a C.sub.3 -C.sub.10 saturated hydrocarbon, which is branched or unbranched, cyclic or acylic, and, preferably, is heptane or cyclohexane. The terpolymers are obtained in high yield, as a white powder, which can be filtered and dried easily.

  • Patent number: 5008038
    Abstract: Solubility of chlorhexidine free base and hydrocarbon substituted lactams in water is substantially enhanced by forming an aqueous solution of a complex of chlorhexidine free base and lactam. This is preferably done by dissolving chlorhexidine free base in lactam and then mixing the resulting solution with water. The resulting aqueous solution contains between about 1 and about 25 wt % of a complex of lactam and chlorhexidine with chlorhexidine being present in amounts between about 0.08 and about 0.25 wt % based on lactam. Lactam used is defined by the formula ##STR1## wherein n is an integer having a value of from 1 to 3 and R is a linear alkyl radical containing from 10 to 14 carbon atoms.

  • Patent number: 4927667
    Abstract: An aqueous process is described for preparing water-resistant coatings of hydrophobic copolymers of a predetermined composition. The hydrophobic copolymers are made from hydrophilic comonomers such as a vinyl lactam and a polymerizable carboxylic acid.
