Preparation of Associative Polyurethane Thickener and Its
AbstractIntroductionExperimentalResults and DiscussionConclusionAssociative polyurethane (PU) thickener has been synthesized by preparing the prepolymer with the reaction of polyethylene glycol (PEG) and isophorone diisocyanate (IPDI), which then endcapping with longchain alkanol. The synthesis process, as well as hydrophilic chain length, theoretical molecular weight, solvent ratio, and thickener percentages, has been researched. The results shows that it reaches the upmost thickening effect when the theoretical molecular weight is under 20, softsegment length is under 4, solvent ratio Chat

Thickeners and Rheology Additives chem tech product

Associative polyurethane thickener. The thickening mechanism of associative polyurethane thickeners is completely different. Due to their hydrophobichydrophilichydrophobic structure they form aggregates in aqueous systems (micelles), whereby e.g. one thickener molecule can be part of two or more micelles linking them physically this way.
