Hillier discloses thermoplastic polymers comprising
nonvulcanized radial block copolymers of the diene-aryl
substituted olefin butadiene-styrene type blended with other
polymeric or copolymeric materials, such as polyesters,
polyester urethane polymers and polyether urethane polymers,
to form plastic compositions which have sufficient clarity,
hardness, tensile strength and elongation to be readily
adaptable for use in composing plastic materials for contact
with parenteral fluids. Hillier teaches that the disclosed
compositions have such a high degree of clarity that they can
replace polyvinylchloride (PVC) as a material in the forming
