    摘要: The invention relates to a papermaking agent system in liquid form, which comprises (i) cationic starch solution, prepared by cooking a starch mixture comprising a starch component and a water component, and (ii) polymer composition, which has anionic and cationic groups and a cationic net charge of >0.1 meq/g. The polymer composition comprises or originates from at least one of constituents a), b) or c). Constituent a) contains an amphoteric polymer, which is a copolymer comprising structural units derived from acrylamide and/or methacrylamide monomers, and anionic and cationic groups attached to the copolymer. Constituent b) contains a first polymer, which is a copolymer comprising structural units derived from acrylamide and/or methacrylamide monomers, and anionic or cationic groups attached to the copolymer, as well as a second polymer, which comprises groups with opposite charge than the first polymer. Constituent c) contains a third polymer, which comprises a copolymer comprising structural units derived from acrylamide and/or methacrylamide monomers, as well as hydrolytically unstable cationic groups attached to the copolymer. Constituent a), b) or c) is added to one of the components of the starch mixture or to the starch mixture before the cooking of the starch mixture, and/or constituent a) or b) is added to the cationic starch solution after cooking of the starch mixture. The invention relates also to the use of the papermaking agent system and to a method for its preparation.

    摘要: This invention relates to a degraded, inhibited cationic starch for use in papermaking systems, which affords improved physical properties, particularly strength. Additionally these derivatives provide easy-to-prepare alternatives totraditional starches, and can even be added directly to the papermaking process without cooking. While the benefits of these starch compositions can be applied to any type of papermaking method, they are especially useful in high shear, high conductivity and recycle systems.

    摘要: The invention relates to novel pharmaceutical forms for antibiotics containing amino sugar, amphotericin B, daunorubicin and doxorubicin, in which the known side effects are reduced and which can be used in a simple manner. The antimycotic agent B is nephrotoxic. The cytostatic agents daunorubicin and doxorubicin are highly cardiotoxic. The novel pharmaceutical forms are antibiotic-starch conjugates, wherein the antibiotic is combined with the polysaccharide at the reducing end thereof by means of a peptide bond. According to the invention, said bond is carried out by means of J2 oxidation of the starch derivative at the reducing end thereof in an aqueous alkaline solution, and by coupling the starch derivative oxidised thereby to the antibiotic in an organic solution. The conjugates obtained are less toxic. The polysaccharide part can be decomposed by serum-null-amylase and the peptide bond can be accessed by an enzymatic attack.
