    摘要: An improved impact modifier for polymers, such as PBT and blends thereof; is disclosed. The impact modifier is a blend of (A) a core/shell additive having a core based on alkyl acrylate, on a polyorganosiloxane rubber or a blend thereof and a shell based on poly(alkyl methacrylate), or on a styrene-acrylonitrile copolymer grafted onto the core; and (B) a linear copolymer which contains from 50 to 85 parts of units derived from ethylene, from 5 to 40 parts of units derived from (meth)acrylic esters, and from 2 to 10 parts of a copolymerizable monomer containing an epoxy group. The impact strength provided by the impact modifier blend is unexpectedly higher than the impact strength provided by each individual component of the blend.

    摘要: The invention relates to compositions of polyvinylidene fluoride (PVDF) and its copolymers that have been modified with an onium salt. The PVDF compositions exhibit an increased melting point, a reduced heat distortion and piezo properties. The improved properties can be further enhanced through annealing, and/or the addition of nanoclays. Additionally, the combination of PVDF, nanoclays and annealing can also produce a PVDF with an increased melting point and piezoelectric properties.

    摘要: The invention relates to a foamed fluoropolymer, preferably a polyvinylidene fluoride (PVDF) structure, such as from Kynar® resins. The foamed structure is continuous self-supporting, sized, and has a dense skin. The foamed structure is manufactured in a process using foaming agents and nucleating agents. The structure is sized into a specific shape during the manufacturing process—requiring a good melt viscosity of the PVDF foam. In one process, a master batch containing the nucleating agent is used. The foamed article could be a sheet, film, profile, tube, pipe, article, rod foam-core structure, or other self-supporting shape. Foamed tubes, pipes, rods, sheets and conduit are especially useful. The foamed structure of the invention provides added value by being lighter weight, more flexible, and more impact resistant than a comparable non-foamed PVDF structure. It also has increased hysteresis, increased insulation properties, reduced dielectric constant, and increased compressibility.
