    摘要: Monovinyl aromatic polymers are modified by reacting with elemental alkali metal and a conjugated diene to produce polymers having branches containing olefinic unsaturation. The olefinically unsaturated branches provide reactive sites which are readily reacted with various substances to obtain numerous variations in the properties of the monovinyl aromatic polymers.
