AbstractWhen rubber‐reinforced thermoplastics are produced, conversion of monomer to glassy polymer takes place in two thermodynamically incompatible phases. Regardless of the chemical nature of the grafting process, monomer which is converted in the glassy phase can never be grafted to rubber simply because it is never in contact with rubber. A simple model has been developed which describes quantitatively the upper limit of grafting arising from the physical nature of the process as a function of conversion and monomer‐to‐rubber ratio in the c
