发明人：FONG DODD W; HOOTS JOHN E
权利人:NALCO CHEMICAL CO
摘要:A polymer having pendant fluorescent groups is prepared by (trans)amidation of a preformed polymer by reaction with an amine-containing organic fluorescent composition of the Formula III Formula III wherein one of R5 and R6 may be hydrogen, and wherein within at least one of R5 and R6, or within R5 and R6 taken together, is an organic fluorescent group wherein the organic fluorescent group includes a polynuclear aromatic ring system. A degree of (trans)amidation derivatization of the polymer is accomplished by heating the admixture of polymer and fluorescent agent for a sufficient period of time. A second amine-containing post-polymerization derivatization agent other than the organic fluorescent composition of Formula III is added to the admixture or to at least a portion of the reaction product of the (trans)amidation derivatization, and is heated therewith to accomplish a degree of sequential or simultaneous post-polymerization derivatization with the second amine-containing post-polymerization derivatization agent.

权利人:BASF SE
摘要:The present application relates to an alkoxylated polymer consisting of (i) triethanolamine (TEA) and/or triisopropanolamine (TIPA) units and (ii) chains of alkylene oxide units, where the components are chosen so as to give rise to a biodegradable polymer with washing power that can be synthesized with reduced dioxane formation. The application is also directed to a cleaning composition comprising the alkoxylated polymer, to the use of the inventive polymer for boosting the primary washing power of washing compositions, to a cleaning method and to the use of (i) triethanolamine (TEA) and/or triisopropanolamine, (ii) ethylene oxide (EO) and (iii) propylene oxide (PO) for low-dioxane production of an alkoxylated polymer.
