  • Patent number: 11692059
    Abstract: The present invention discloses a ketone-aldehyde modified resin and the preparation process thereof. The ketone-aldehyde modified resin comprises a ketone-aldehyde modified unsaturated polyester, a ketone-aldehyde modified unsaturated alkyd or the combination thereof, and wherein the said resin has ketone-aldehyde moieties. The process of the said resin comprises the steps of: reacting unsaturated polyester-forming and/or unsaturated alkyd resin-forming monomer components with a ketone-aldehyde resin. The present invention also discloses a coating composition comprising the said resin as well as a coated article. The ketone-aldehyde modified resin and the coating composition achieve significantly improved fast drying effect, while other properties are not observably impaired or even improved.

  • Publication number: 20230092694
    Abstract: A vulcanizing agent is added during the processing of a polymer, and can form a crosslinking structure network in the polymer, thereby improving the mechanical properties of the material. Furthermore, the crosslinking agent can also de-crosslink the polymer material at a high temperature, and after being cooled, same can be crosslinked again to produce a network structure, thus endowing the polymer material with thermoplasticity for repeated processing.
