Abstract: A multicomponent polymer blend composition is prepared by intimately mixing a polyamide, a selectively hydrogenated monoalkenyl arene-diene block copolymer, and at least one dissimilar engineering thermoplastic resin under such conditions that at least two of the polymers form at least partial continuous network phases which interlock with the other polymer networks and therefore results in a desirable balance of properties.

Abstract: A multicomponent polymer blend composition is prepared by intimately mixing a polyolefin, a selectively hydrogenated monoalkenyl arene-diene block copolymer, and at least one dissimilar engineering thermoplastic resin under such conditions that at least two of the polymers form at least partial continuous network phases which interlock with the other polymer networks and therefore results in a desirable balance of properties.

Abstract: A multicomponent polymer blend composition is prepared by intimately mixing a halogenated thermoplastic, a selectively hydrogenated monoalkenyl arene-diene block copolymer, and at least one dissimilar engineering thermoplastic resin under such conditions that at least two of the polymers form at least partial continuous network phases which interlock with the other polymer networks and therefore results in a desirable balance of properties. These blends have an unobviously high heat distortion temperature relative to the improved impact strength.

Abstract: Polymeric blends having an unobviously high structural integrity and an improved balance of properties are prepared by intimately mixing certain selectively hydrogenated block copolymers with polyaryl polyethers and aromatic polysulfones thereby forming at least partial continuous networks which interlock.

Abstract: A multicomponent polymer blend composition is prepared by intimately mixing a polyacetal, a selectively hydrogenated monoalkenyl arene-diene block copolymer, and at least one dissimilar engineering thermoplastic resin under such conditions that at least two of the polymers form at least partial continuous network phases which interlock with the other polymer networks and therefore results in a desirable balance of properties. These blends have an unobviously high heat distortion temperature relative to the improved impact strength.

Abstract: Polymeric blends having excellent dimensional stability and an improved balance of properties are prepared by intimately mixing certain selectively hydrogenated block copolymers with polymers and copolymers of 4-methyl-1-pentene under conditions where at least partial continuous networks which interlock are formed.

Abstract: Polymeric blends having an unobviously high structural integrity and an improved balance of properties are prepared by intimately mixing certain selectively hydrogenated block copolymers with certain acetal resins thereby forming at least partial continuous networks which interlock.

Abstract: Polymeric blends, covering the range from rubber-like to flexible mechanical behavior, having outstanding resistance to shrinkage and distortion on heat aging, resistance to ozone, good tensile properties, resilience, processability, as well as a combination of toughness and flexibility are comprised of certain selectively hydrogenated block copolymers and polyamide polymers.
