Abstract
<PICT:0927501/IV(a)/1> In a process for the continuous production of block copolymers, graft polymers or graft copolymers, using a screw extruder (as shown in Fig. 1) having varying thread pitch and/or depth of thread, a monomeric compound containing an olefinic double bond and capable of polymerization under the influence of free radicals is metered through an opening 6 in the casing 3 of the extruder and a thermoplastic high polymer is fed to the inlet 1 of the extruder, the said polymer being masticated by the screw whereby its molecules are ruptured to yield free radical. The process of Specification 857,797 may be performed using the extruder shown in Fig. 1.
