A continuous process for the production of an elastomer-modified
thermoplastic is disclosed. The process entails (i) obtaining graft
elastomer (D) having residual moisture content of 1 to 50 wt. %,
particularly 5 to 50 wt. %, particularly preferably 10 to 40 wt. %, (ii)
introducing (D) and thermoplastic resin (B) through an inlet to a reactor
operating under conditions calculated to melt (D) and (B) and to remove
organic volatile components C) to produce a molten blend, the reactor
being equipped with a plurality of kneading bars, that convey a portion
of the molten blend towards the reactor inlet.
