Block copolymers are obtained from aromatic diisocyanates and vinyl monomers, such as styrene, isoprene, and methyl methacrylate via anionic polymerization, using w-butyllithium as initiator (71). Since TDI imdergoes selective reaction through the nonhindered isocyanato group poly(butadiene-6Zoc -imide) block copolymers are obtained (72). [Pg.4155]

Lastly, mention will be made of two further amide block copolymer syntheses not mentioned above. The first employs living polymer anions from styrene, isoprene or methyl methacrylate to initiate the polymerization of isocyanates to diblock polymers containing nylon 1 sequences. In this approach, selective polymerization can be achieved at the unhindered isocyanate group of diisocyanates such as tolylene 2,4-diisocyanate to give products with pendant NCO groups (32) which are crosslinkable with diols to give tough resins.
