  • Patent number: 10584222
    Abstract: Provided in the present invention are a resin composition and a pre-preg and a laminate using the composition. The resin composition comprises: (A) a prepolymer of a polyolefin resin and a bifunctional maleimide or a multifunctional maleimide; and, (B) vinyl thermosetting polyphenylene ether, where with the weight of the prepolymer of the polyolefin resin and the bifunctional maleimide or the multifunctional maleimide being 100 parts by weight, the weight of the vinyl thermosetting polyphenylene ether is 200 to 1000 parts by weight. The present invention, by employing the prepolymer of the polyolefin resin and the bifunctional maleimide or the multifunctional maleimide, solves the problem of incompatibility of the bifunctional maleimide or the multifunctional maleimide with the polyolefin resin and vinyl thermosetting polyphenylene ether. An aqueous glue solution so mixed is uniform and consistent, the pre-preg has a uniform expression, and a substrate resin area is free of a phase-separation problem.

  • Patent number: 10584204
    Abstract: A process for producing polyamides makes flow guidance within the process more efficient. In some respects, the process is based on the polymerization of lactam to a polyamide-containing polymer melt, the subsequent granulation of the polymer melt to polyamide granules using granulation liquid, and the subsequent extraction of monomeric and oligomeric constituents from the PA granules in an extraction column. In some examples, a temperature of the granulation liquid before being fed into an extraction liquid stream is lower than a temperature of the extraction liquid stream before the granulation liquid is fed into the extraction liquid stream. The invention relates also to a device for carrying out processes such as this one.
