Abstract: Aqueous vinyl ester/acrylate copolymer emulsions possessing enhanced wet pick strength in paper coating compositions comprise a vinyl ester/acrylate copolymer colloidally dispersed in an aqueous medium, the copolymer consisting essentially of (a) a vinyl ester of a C.sub.1 -C.sub.12 alkanoic acid, (b) 2 to 50 wt % of an alkyl acrylate, and (c) 0.1 to 10 wt % of an ethylenically unsaturated mono- or dicarboxylic acid or half ester thereof. The copolymer is prepared by an aqueous emulsion polymerization process comprising the use of a stabilizer system consisting essentially of an alkylphenoxy polyethoxy ethanol and an anionic surfactant and, in the preferred embodiment, the use of a seeding procedure.

Abstract: Nonwoven fibrous sheets impregnated with latices of polyvinyl acetate or its copolymers containing polyvinyl alcohol, intended for use in pre-moistened condition as skin cleansing tissues, are folded and packaged in closed containers or in individual sealed water impervious envelopes; said packaged sheets being maintained in contact with a dilute aqueous solution of a precipitating or gelling agent for polyvinyl alcohol, such as boric acid. The agent imparts improved wet tensile strength to the sheet during storage and use by the consumer but permits the sheet to be safely disposed of, after use, by flushing in plain water without danger of clogging the plumbing system.

Abstract: Nonwoven fibrous sheets bonded with polyvinyl alcohol, intended for use in pre-moistened condition as skin cleansing tissues, are folded and packaged in closed containers or in individual sealed water impervious envelopes; said packaged sheets being maintained in contact with a dilute aqueous solution of boric acid. The boric acid imparts improved wet tensile strength to the sheet during storage and use by the consumer but may be safely disposed of, after use, by flushing in plain water without danger of clogging the plumbing system. Instead of boric acid solution, one may employ for the indicated purpose a non-alkaline aqueous solution of a salt which acts as a precipitating or gelling agent for polyvinyl alcohol, said salt being one having an acid to neutral pH on hydrolysis.
