Samenvatting

Alkyd-acrylic hybrids were prepd. by polymg. the acrylic monomers in the presence of colloidal alkyd droplets. Polymn. in the presence of alkyd caused a retardation of the polymn. through radical delocalization following radical transfer to the unsatd. groups of the fatty acids in the alkyd. The conversion could be raised to nearly 100% by adjusting the reaction conditions. The application properties of hybrids prepd. according to this method could be varied over a broad range by changing either the acrylic component, the alkyd component, or their ratio. The homogeneity of the hybrids differed from blends of acrylic dispersions and alkyd emulsions, as was shown by the MFFT. Good film formation was found without the use of co-solvents. Mixing on microscale of alkyd polymer and acrylate polymer, however, could not be proved. In some cases a true synergistic behavior was obsd., where the hybrid had properties superior to those of the acrylic polymer and the alkyd
