Generally speaking, the present invention is a water-soluble copolymer film comprising a hydrolyzed copolymer of vinyl acetate and a second monomer, the resultant polyvinyl alcohol copolymer having a degree of hydrolysis, expressed as a percentage of vinyl acetate units converted to vinyl alcohol units, of from about 90% to 100%. The second monomer is preferably selected from the group of monomers having carboxylate functionality or sulfonate functionality. The resulting water-soluble copolymer film is disclosed for use in making pouches to contain a unit dose of liquid detergent, such as a liquid laundry detergent. However, it is an aspect of the copolymer film that film solubility is not significantly affected adversely by the detergent. Such film produces pouches having a greater storage shelf-life over prior art water-soluble film.

New anionic surfactants and methods of preparation which are derived from aromatic or substituted aromatic molecules and alkenesulfonic acid. Wherein the aryl compound is alkylated and sulfonated in one-step with an alkene sulfonic acid prior to sulfonic acid neutralization.

The invention relates to a microemulsion heavy wax crystal emulsifying dispersant applied to an oil well for tertiary oil recovery, and is mainly used for solving the problem that the oil production rate is influenced due to the high return pressure and the short thermal washing period of the oil recovery well caused by that serious wax precipitations are generated by the oil well which contains thickened oil and is high in polymer flooding and viscosity. The emulsifying dispersant is prepared from the following components by weight percent: 1% to 3% of high-molecular polymer wax inhibitor, 13% to 25% of organic aromatic solvent, 1% to 3.5% of emulsifying agent, 8% to 12% of sulfonate, 10% to 12.5% of alcohol, 10% to 20% of demulsifier and 25% to 35% of water. The emulsifying dispersant has the dual effects of eliminating and preventing the waxy bitumen colloid precipitations with long molecular chains or high carbon number in crude oil from being precipitated, so that the wall sticking quantity of condensate oil is greatly decreased; the running load of the oil well is reduced; and the well washing period is prolonged. Thus, the oil production rate is improved.
