Claim:
1. A process for preparing a composition comprising a) a polyol component comprising a polyol with an average molecular weight of from 2000 to 12000 and an average functionality of 1.5 to 6; and b) a core shell rubber comprising a rubber particle core and a shell layer wherein said core shell rubber has a particle size of from 0.01 μm to 0.5 μm, the process comprising dispersing the core shell rubber into the polyol component with a high shear mixer in a dispersion zone under dispersion conditions wherein said dispersion zone does not contain a solvent and wherein said dispersion conditions comprise a dispersion temperature of 40° C. to 120° C., a Reynolds Number greater than 10, and a dispersion time of from 30 minutes to 480 minutes.
