    Abstract: An emulsion polymerization process of manufacturing a graft polymer composition with a reduced residual monomer content includes feeding a vinyl aromatic monomer, an unsaturated nitrile, and a first portion of an initiator to a reactor having a temperature of 50 to 63° C., the reactor containing an initial reaction system comprising water and a diene emulsion. After 10% to 35% of the first portion of the initiator has been added, the reactor temperature is increased to 65 to 85° C. The polymerization reaction runs for 0 to 30 minutes, then a second portion of the initiator and a third monomer are added, and the reaction is allowed to proceed for a second non-charging reaction time to produce the graft polymer composition. In the process, the vinyl aromatic monomer and the unsaturated nitrile are fed to the reactor in 10 to 40 minutes. The process time can be less than 145 minutes.

    Abstract: The disclosure provides a flushing process for removing polymer fouling from a reactor including a gas distributor proximal to the bottom thereof and an internal condenser proximal to the top thereof, the method including, for a first flushing time period, injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the internal condenser to induce an upward movement of flushing solvent, the withdrawn flushing solvent containing a first polymer content. After the first flushing time period is complete, for a second flushing time period, the process includes injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the gas distributor to induce a downward movement of flushing solvent, the withdrawn flushing solvent containing a second polymer content.
