摘要:Polyurethane synthesis composition using a polymeric emulsifier having a backbone consisting of a copolymer of 4-12C unsaturated dicarboxylic acid or anhydrides and 2-40C olefins, with polyoxyalkylene side chains derived from 2-20C oxiranes. A polyurethane (PU) synthesis composition containing, as emulsifier, a polymer (T) with (at least) a copolymer backbone (TR) derived from 4-12 carbon(C) unsaturated dicarboxylic acid(s) and/or their anhydrides (TR1) and 2-40 C olefin(s) (TR2), and having polyalkylene oxide side chain (TP) derived from 2-20 C oxirane(s) (TP1), together with at least two compounds (a) comprising at least two reactive hydrogen atoms, at least one of which is insoluble. Independent claims are also included for: (a) a process for the production of synthesis composition by contacting the components in presence of a polymer; (b) a PU synthesis composition obtained; (c) a polyurethane obtained by bringing the synthesis composition into contact with a polyisocyanate; and (d) moldings, fibers, coatings, paint, sheets and a foam made from the PU compositions.

标题 :Improved method for synthesis of polyamide composite membranes
发明人：MARIËN Hanne; VANKELECOM IVO; HERMANS SANNE
权利人:UNIV LEUVEN KATH
摘要:The present invention provides a method for the preparation of thin film composite (TFC) membranes, preferably solvent resistant TFC membranes, by interracial polymerization (IFP), more in particular solvent resistant TFC membranes wherein a thin PA-layer is deposited on a porous support membrane. Said method comprises the replacement of the aqueous and/or the organic solvent in the IFP method by an ionic liquid (IL) as solvent for the monomers which form said TFC membranes, to alter the top layer morphology, thickness and crosslinking degree.
