  • Patent number: 11643520
    Abstract: The invention relates to low density fluoropolymer foam, and preferably polyvinylidene fluoride (PVDF) foam, such as that made with KYNAR PVDF resins, and articles made of the foam. The foam is produced by adding microspheres containing blowing agents to the polymer and processing it through an extruder. The microspheres consist of a hard shell containing a physical blowing agent. The shell softens at elevated temperatures and allows the expansion of the blowing agent, and microsphere to create larger voids within the polymer matrix. By proper control of the polymer composition, viscosity, processing temperature, blowing agent selection, loading ratio, and finishing conditions, useful articles such as foamed PVDF pipe, tube, profiles, film, wire jacketing and other articles can be produced. The microspheres may be added to the fluoropolymer matrix by several means, including as part of a masterbatch with a compatible polymer carrier.

  • Patent number: 11608416
    Abstract: A method for synthesizing an aliphatic polyester block copolymer regulated by carbon monoxide. The method uses an organic cobalt metal complex as a convertible catalyst and includes: first regulating an anionic ring-opening copolymerization reaction between an aliphatic acid anhydride and an epoxy compound; then using carbon monoxide as a conversion agent for conversion to obtain a catalyst having a new catalytic active site; and regulating a vinyl monomer to perform active free radical polymerization to obtain an aliphatic polyester block copolymer having a controllable structure. The described synthesis method uses a convertible catalyst and a conversion agent, combines two controllable polymerization reactions which have different but compatible mechanisms, and obtains a block copolymer by means of a “one-pot” reaction.
