Patent ID: 7368061

Claim:
A continuous process for the production of an elastomer-modified thermoplastic comprising (i) obtaining graft elastomer D) that includes a grafted phase A), said D) having residual moisture content of 1 to 50 wt. %, (ii) partially filling a compounding reactor with the graft elastomer D) and a thermoplastic resin B) through at least one inlet of the compounding reactor and operating the partially filled compounding reactor under conditions calculated to melt D) and B) and to remove organic volatile components C), and (iii) collecting a molten blend comprising A), D) and B), said reactor being equipped with a housing having a surface, a plurality of kneading bars that provide kneading action and an exit zone, said kneading bars conveying a portion of the molten blend towards the reactor inlet; and wherein the throughput of the molten blend comprising A), D) and B) through the compounding reactor per liter of processing capacity is no more than 5 kg/h.
