Our Sokalan® types belong chemically to the class of anionic water soluble polymers. They are either homopolymers or copolymers of acrylic sources. Sokalan® types are used as scale inhibitors or dispersing agents for stabilisation of dispersions. The Sokalan® PA/CP range Acrylic acid can be polymerized to yield water-soluble homopolymers. Our (davor: BASF’s) range of acrylic homopolymers for water treatment and for other industrial applications is marketed under the Sokalan® PA trademark. The properties of copolymers can be engineered by judicious selection of additional comonomers. Our (davor: BASF’s) range of acrylic copolymers are designated Sokalan® CP. The alphanumeric code indicates the chemical form in which products are supplied. The free acids in the Sokalan range, such as Sokalan® PA 110 S, are designated by the suffix “S”. Partially neutralized acids are designated by the suffix „PN“, such as Sokalan® PA 25 CL PN. The Sokalan® HP range The Sokalan® HP grades are polymers with a distinct set of properties. Some of them are used to obtain special effects like Sokalan® HP 56 K as the market standard dye transfer inhibitor (DTI). They stabilize the soil removed from the fibres during the washing process and prevent it from being redeposited on clean fabrics. Sokalan® HP grades differ from cellulosic antiredeposition agents such as carboxymethyl cellulose (CMC) and hydroxypropylmethyl cellulose (HPMC) in that they perform very well in the presence of coloured soil. They are particularly effective in preventing reactive and direct dyes from being transferred, especially those that contain sulfonyl-, hydroxyl- or amino groups.
