Abstract
Block polymers of the star type contain a central core of crosslinked bisunsaturated compound and a plurality of functionalized branches attached to the core, each branch containing at least a terminal portion of polymerized alkyl methacrylate, polymerized through the ethylenic unsaturation of the methacrylate moiety. The polymers are useful in adhesive formulations and as viscosity index improvers for hydrocarbon fluids.
