OLIGOMERIC COAGULATION AID AND DISPERSION AID

A composition for dispersing multilayer polymers has an oligomer prepared from at least one alkyl (meth)acrylate monomer in the presence of a chain transfer agent. The oligomer has a number average molecular weight of less than 10,000 g/mol and a glass transition temperature, Tg, as measured by DSC,...

Beschreibung
Zusammenfassung:	A composition for dispersing multilayer polymers has an oligomer prepared from at least one alkyl (meth)acrylate monomer in the presence of a chain transfer agent. The oligomer has a number average molecular weight of less than 10,000 g/mol and a glass transition temperature, Tg, as measured by DSC, less than a coagulation temperature of a composition comprising the oligomer and a multilayer polymer, wherein the coagulation temperature is based on an average particle diameter of 200 microns. A composition containing the oligomer and a multilayer polymer, such as an acrylic core-shell polymer or methacrylate butadiene styrene core-shell polymer, and a resin composition are also disclosed.
