Abstract: A process for the manufacture of benzene-free maleic anhydride/lower alkyl vinyl ether polymer having a specific viscosity ranging from about 1.0 to about 5.5 by premixing maleic anhydride and the alkyl vinyl ether in a mole ratio of between about 1:1.1 and about 1:2 in a cosolvent mixture of lower alkyl substituted benzene, a C6-8 alkane, a saturated lower alkyl ether with a lower alkyl vinyl ether as cosolvent and reacting the monomeric complexed mixture at elevated temperature and pressure in continuous contact with a peroxide initiator wherein the specific viscosity is controlled by adjusting the amount of lower alkyl vinyl ether in the cosolvent mixture. The polymeric product is recovered from the resulting slurry by vacuum drying.

Abstract: A pressure sensitive hot melt adhesive contains thermoplastic rubber such as styrene isoprene copolymer, a copolymer of vinylpyrrolidone and vinylacetate, fatty acid and, usually, tackifying resin. The composition is water soluble or water dispersible which facilitates removal of labels by washing and recycling of scrap material in label production. The composition gives better properties, especially peel strength, than other water-soluble or dispersible hot melt compositions.

Abstract: What is provided herein is a stabilized, aqueous, film-forming, antimicrobial composition of hydrogen peroxide. The active, oxygen-generating hydrogen peroxide component in the composition is stabilized in an aqueous-polyol solvent system of predetermined polarity containing PVP. In contrast, similar formulations without PVP experienced a loss of peroxide activity upon standing. Suitably, the composition herein includes about 1-20 % by weight hydrogen peroxide, about 0.1-50 % by weight PVP, and about 0.1-80 % by weight of a polyol, the rest being water. Preferably, about 5-20 % by weight of water is present in the composition. Additional solvents may be included therein, such as alcohols, ether oxides, esters, triglycerides of fatty acids, hydrocarbons, N-vinyl lactams, silicone oils, and polyether oligomers.
