Abstract:
The present invention relates to a method for preparing a superabsorbent polymer. According to the present invention, the method for preparing a superabsorbent polymer carries out, with respect to a polymer obtained by polymerizing ethylenically unsaturated monomers, a re-granulation step by mixing water and a compound of a specific chemical formula. According to the present invention, provided is a method for preparing a superabsorbent polymer, capable of improving the quality of a final resin since the moisture retention capacity thereof is improved and the amount of remaining monomers is reduced.

Abstract:
The invention relates to amphiphilic polyacid (meth)acrylic copolymers having C8-C20 aliphatic grafts, particularly those from terpenic derivatives. The copolymers are usable as surface-active agents in different manufactured products, such as fragrances, cosmetics, detergents, paints, coatings, food products, textiles, laundry detergents, and pharmaceutical products. Said copolymers make it possible, in particular, to produce transparent emulsions from terpenic derivatives and from fragrance concentrates.
Abstract:
The present invention provides a method of manufacturing an automatic dishwashing detergent product, said product being provided as a discrete dosage unit and comprising a continuous, non-aqueous gel phase, comprising manufacturing said gel phase by a method comprising free radical polymerisation of monomer(s) in a non-aqueous reaction mixture to form a polymeric builder; wherein said reaction mixture comprises: at least one non-ionic surfactant which is an optionally end-capped alcohol alkoxylate; and one or more monomers comprising acrylic acid and optionally one or more further α,β-ethylenically unsaturated acids, wherein no more than 0.1 wt % of the total amount of the monomer(s) are crosslinking monomer(s).
Abstract:
본 발명은 흡수배율저하 정도가 낮은 고흡수성 수지 및 그 제조 방법에 관한 것이다. 구체적으로, 고흡수성 수지 제조시 단량체 대비 개시제의 양을 최소화하여 분자량이 큰 주사슬을 가지고 높은 겔강도를 유지하는 균일하게 가교된 아크릴 수지를 제조함으로써, 시간 경과후에도 가압시 수분이 베어나오지 않는 리웻 방지 능력이 뛰어나 피부발진을 방지할 수 있는 고흡수성 수지 및 그 제조방법이 제공된다.
Abstract:
Die vorliegende Erfindung betrifft eine Dispersion zur Herstellung von mit Harz imprägnierten Papieren, wie sie für die Herstellung von scheuerfesten (mikrokratzfesten)Oberflächen, wie etwa von Laminatfußböden, Möbeloberflächen oder Schichtstoffen (CPL, HPL) verwendet werdenkönnen. Die Erfindung betrifft zudem ein entsprechendes Verfahren zur Herstellung derartiger Oberflächensowie entsprechend hergestellte Produkte. Die Dispersion enthält dabei bsp. (in Gewichtsprozent) 30 bis 75 % Wasser und 10 bis 65 % Korundpartikel mit einer Korngröße von F400 bis F2000 sowie weitere Hilfsstoffe in geringer Menge. Diese Dispersion kannflüssige Aminoharzmischung eingebrachtwerden,um Papier zu imprägnieren.
Abstract:
The present invention relates to a continuous process for the manufacture of highly-branched homo- or copolymers of C 3 -C 8 ethylenically unsaturated mono- or dicarboxylic acid as well as the anhydrides and salts thereof (monomer A) by means of free-radical polymerization of monomer A and optionally water-soluble, monethylenically unsaturated comonomers (monomer B) in an aqueous medium in the presence of at least one water-soluble initiator, wherein the polymerization takes place in at least one tubular reactor segment.
