摘要:
Polymeric blends having structural integrity at unobviously high temperature and an improved balance of properties are prepared by intimately mixing certain selectively hydrogenated block copolymers with certain thermoplastic saturated polyesters under conditions where at least partial continuous networks which interlock are formed.
摘要:
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.

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.
摘要:
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.
摘要:
Polymer blends exhibiting improved mechanical properties of strength and toughness comprise blends of a major proportion of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with minor proportions of a polymeric polyamide and a polymer of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid having an optional third monomer and optional partial neutralization of the carboxylic acid groups by non-alkali metal.

The invention relates to molding compounds modified with a high 1,2 unsaturated carboxylated styrene-butadiene block polymer and a saturated styrene-alpha-olefin block polymer, said molding compounds containing an unsaturated crosslinkable resin, ethylenically unsaturated monomer, filler, reinforcing agent, catalyst, and thickener.

A polymer blend having excellent impact strength, even at zero moisture level, comprises the blend of 100 parts by weight of a polyamide and less than 50 parts by weight of a selectively hydrogenated monoalkenyl arene-conjugated diene block polymer.
摘要:
A multicomponent polymer blend composition is prepared by intimately mixing a nitrile barrier resin, 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.
