Abstract
Binder, coating, and adhesive compositions having surprising film build, flow, leveling, and adhesive wet tack are provided by an aqueous dispersion comprising polymer particles having a central core surrounded by lobes. Also disclsoed are the uses and process of preparation of these unique particles.
Claims30
An aqueous dispersion comprising multilobal polymer particles where said multilobal polymer particles comprise a polymeric central core and at least two polymeric lobes on said polymeric core, said lobe polymer being compositionally different from said core polymer, and where the weight ratio of lobe polymer to core polymer ranges from about 2 to 1 to about 500 to 1, and where said dispersion of said multilobal polymer particles is useful in binder, coating and adhesive compositions.
Multilobal polymer particles comprising a polymeric core and at least two polymeric lobes on said polymeric core, where the lobe polymers and said core polymer are compositionally different and where the ratio of lobe polymer to core polymer ranges from about 2 to 1 to about 500 to 1 by weight.
