  • Shape memory polymer articles with a microstructured surface
    Patent number: 10279069
    Abstract: A shape memory polymer article is disclosed. The article may include a surface having a microstructure and it may include a shape memory polymer. The shape memory polymer may include a copolymer network. The copolymer network may be formed from the reaction product of a free radically polymerizable siloxane having greater than one functional free radically polymerizable group and at least one (meth)acrylate monomer.
    Type: Grant
    Filed: November 15, 2011
    Date of Patent: May 7, 2019
    Assignee: 3M Innovative Properties Company
    Inventors: Mieczyslaw H. Mazurek, Robert K. Galkiewicz, Audrey A. Sherman, James R. Starkey, Wendi J. Winkler, Haiyan Zhang, Jeffrey M. Olofson
  • Methods for changing the shape of a surface of a shape memory polymer article
    Patent number: 8236226
    Abstract: Methods for changing the shape of a surface of an article are disclosed. The methods may include providing a liquid polymer precursor, casting the precursor against a first tool assembly, curing the precursor to form a shape memory polymer substrate, deforming one or more surfaces of the substrate, and mobilizing the shape memory polymer to shift the deformed surface of the substrate from a deformed shape to a pre-set shape.

  • Catalysts and initiators for polymerization
    Patent number: 5514728
    Abstract: Salts having a cationic portion of either a mono-, polyvent metal center, onium salts or organometallic salts and a nonnucleophilic anion are useful as catalysts and initiators that may be photochemically or thermally-activated, and polymerizable compositions containing such catalysts and initiator salts and at least one of a cationic or free-radical addition polymerizable monomers, or catalyzed step-growth polymerizable monomers.
