摘要

A combination of water soluble Polymer Film and Additive, which comprises: (a) a water soluble Film,Formed from a Copolymer Resin of vinyl Alcohol and Anionic comonomer molar of a nonhydrolyzable, as (i) unsaturated acids, such as Acrylic acid, methacrylic acid,Cis - 3 - 2 - butanoic acid, butanoic acid, cinnamic, fenilcinamico, pentenoico, metilenmalonico, alkali metal and ammonium salts and Derivatives of acyl Halide; (ii) esters, unsaturatedAmides acyl Halide and the structure (i) wherein R1, R2 and R3 are H or alkyl or aryl groups, Hydroxy alkyl; n is 0, 1, and X is - C (o) - Where nr4r5 Coy or R4 is H or alkyl, aryl,Alquenilo, hidroxialquilo, oxialquilo or cianoalquilo, R5 is H or an alkyl, aryl or hidroxialquilo; e and X is a Halide; or where is co2r4, R4 is alkyl, aryl, alquenilo, hidroxialquilo,Oxialquilo or cianoalquilo unsaturated dibasic; (iii) the structure (ii), where P and q are enterosde 0 - 5; R6 and R7 are hu00d1 or alkyl or aryl; (iv) Acyclic and cyclic anhydride, Ester,Amide and imide Derivatives of the structure (ii); (V) unsaturated sulphonic acid and its derivatives; (VI) mixtures of the same, including the film a plasticizer; and (b) an Alkaline compositionNa or containing borate, partially enclosed by the film where the film is dissolved When placed in an aqueous medium, or Releasing Alkaline composition containing borate.
