Abstract (en)

[origin: WO0200787A1] This invention relates generally to linear tetrablock copolymer compositions and their use in road-marking applications. These tetrablock copolymers contain polystyrene, polyisoprene and polybutadiene components. Road-marking compounds prepared from these copolymers further contain a hydrocarbon resin or rosin ester or both. These block copolymer are readily mixed using melt-mixing techniques, thus, avoiding both powder grinding and high-shear stirring.
