Polyglykol M 500 PU

Polyglykol M 500 PU by Clariant is a linear, mono hydroxy-functional polyethylene glycol monomethyl ether (M-PEG). It has low diol content to limit the formation of crosslinking diesters. It offers low alkali and low water content. It shows typical chemical reactions of alcohols/diols and a very low evaporation rate. When reacted with unsaturated monomers like acrylic or methacrylic acid, esters are formed which can be copolymerized in order to increase hydrophilicity and improves dispersing properties of polymers in water. It is esterified with methacrylic acid to yield the corresponding polyglycol mono methacrylates which are used for the polymerization of polycarboxylate superplasticizers. Polyglykol M 500 PU is produced for polyurethane applications.
