  • Non-Swelling Hot Melt Adhesive
    Publication number: 20210238457
    Abstract: Provided herein is a hot melt pressure sensitive adhesive comprising one or more styrene block copolymers, a tackifier, and polyisobutylene plasticizer, wherein the adhesive contains less than 1 wt % of a plasticizer oil. The adhesive can be used in a label construction along with a facestock such as a polyethylene facestock, wherein the swelling factor of the facestock is reduced as compared to the swelling factor of the facestock in labels that include a plasticizer oil. Also provided are methods for producing and using the hot melt adhesive, and articles labeled with the hot melt adhesive.

  • Production of isotactic and regiorandom polypropylene based polymer and block copolymers
    Patent number: 8039655
    Abstract: One step ortho-alkylation of anilines with styrenes to give chiral anilines is obtained using a strong acid catalyst, e.g. CF3SO3H. Condensation of the product to give ligand and metallation gives complex which catalyzes polymerization of propylene to give isotactic propylene or regiorandom propylene of low PDI or blocks thereof, depending on polymerization temperature.
