ABSTRACT:
The present invention relates to a method for preparing polymer composites. The method includes providing a mixture of concentrated emulsions and polymerizing the mixture of concentrated emulsions under conditions effective to form a polymer composite. The mixture of concentrated emulsions includes either a divinyl-terminated macromonomer and a first partially polymerized concentrated emulsion of a first monomer or a first partially copolymerized concentrated emulsion of a divinyl-terminated macromonomer and a first monomer. The mixture of concentrated emulsions further includes either a second partially polymerized concentrated emulsion of a second monomer or a second partially copolymerized concentrated emulsion of a divinyl-terminated macromonomer and a second monomer. Using the methods of the present invention, polymer blends and/or polymer networks containing compatibilizers can be produced. Since the polymers which are blended and the compatibilizers are generated simultaneously in situ, the methods of the present invention, compared to conventional melt-mixing techniques, are simpler and more flexible and produce compatibilized blends having improved mechanical and optical properties.
