Graft copolymers with poly(vinyl chloride) backbones and controlled amounts of polystyrene, poly(1,2‐butadiene), or poly(1,2‐butadiene–styrene) are prepared by carbanionic deactivation. Synthesis is by two methods: a classical step‐by‐step anionic polymerization technique and a new one‐apparatus technique. The reaction products are characterized by osmometry, selective extraction, and gel permeation chromatography to test the consistency of the three methods. A few words are said about the yields of grafting compared with temperature, size, and nature of carbanions.
