摘要：By means of the twin-screw extruder as the reactor, diglycol dimethyl ether (2 G) as the polar additive, and mixed styrene (S) and isoprene (I) as the monomer, a S/I copolymer was synthesized by reactive extrusion, initiated by organic lithium. It is found by results of 1H-NMR, GPC and DMA, that with the adding and increasing of 2 G, the content of 3, 4-IP and random styrene of copolymers are increased; the length of PS segments is decreased, and a PS block is on the end of the molecule chains; the Tg of continuous and disperse phases is increased, and the compatibility of different phases is improved.
