  • Patent number: 8633278
    Abstract: The invention relates to novel, stable bi-molecular cationic inverse emulsion polymers (W/O) with both different molecular weights and cationic activities that are assembled via an “in situ” emulsion polymerization of a high molecular weight cationic polymer in the presence of a low molecular weight polymer in the aqueous phase. The low molecular cationic polymer is produced in a pre-polymerization in solution. The novel, stable cationic water-in-oil emulsion is easy invertible and useful as flocculant, dewatering aid and retention aid in papermaking.

  • Publication number: 20130209388
    Abstract: The presently disclosed and claimed inventive concept(s) relates to a conditioning composition additive for use on keratin substrates in order to provide immediate as well as long lasting benefits to the keratin substrate in conditioning systems, such as leave-on and rinse off conditioners, for hair and skin, or for imparting greater water resistance to such personal care compositions as sunscreens or cosmetics. The presently disclosed and claimed inventive concept(s) also relates to a conditioning composition containing the conditioning composition additive and a method of applying the conditioning composition additive.

  • Publication number: 20080302497
    Abstract: The present invention relates to flat paper products having an increased relative wet strength and softness, a method for the production of the same and also the use of paper products of this type in the form of tissue products. This is achieved by a cross-linkage of the cellulose fibres contained in the paper product with a cationic graft copolymer which is constructed on the basis of polyethyleneoxide- or polyethyleneglycol segments and polyethyleneimine segments.

  • Publication number: 20040236017
    Abstract: The invention relates to a method for the production of grafted copolymers with a skeleton formed from starch or the derivatives thereof. Production occurs by means of tert-alkylazocyanocarboxylic acid esters of starch which are coupled by radical reaction with vinyl monomers. The invention also relates to grafted copolymers of starch, the dispersions thereof and the use of said grafted copolymers.
