Abstract: Associative polyurethane(PU) thickener was prepared with polyethylene glycol(PEG)and disneyanate as raw materials. Effect of different process conditions on the properties of PU thickener was studied. Influence of molecular weight of PU thickener on the particle size and morphology of PU dispersions was analyzed.Furthermore, effect of PU thickener on the film-forming performance of PU was discussed in detail.
