Abstract: Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, and polymeric materials formed from the reaction mixtures are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds with a single carbon atom between the two dithiocarbamate or dithiocarbonate groups. Polymeric materials such as homopolymers, random copolymers, and block copolymers can be prepared using the controlled radical initiators.

Abstract: Adhesive compositions are provided that include a crosslinked silicone gel, a hydrophilic component dispersed in the silicone gel, and an antimicrobial agent dispersed in the silicone gel. The adhesive composition is readily applied to (and removed from) skin, and has desirable hydrophilic and antimicrobial properties. Advantageously, the hydrophilic component in the crosslinked silicone gel is not readily extractable (e.g., into a pH 7 buffer). Surprisingly, the combination of hydrophilic component with antimicrobial agent in the crosslinked silicone gel can provide a synergistic level of antimicrobial activity.

Abstract: Pressure sensitive adhesives made from a polymodal asymmetric elastomeric block copolymer, a tackifying resin and liquid polyisoprene are provided. Articles containing these pressure sensitive adhesives including protective sheeting, labels, laminated adhesives, tapes and adhesive films are described. The pressure sensitive adhesive based on polymodal asymmetric block copolymer described herein exhibits good adhesion on various substrates such as stainless steel (SS), polypropylene (PP) and high density polyethylene (HDPE) and enhanced high temperature shear without the effect of electron beam or UV curing.

Abstract: A pressure sensitive adhesive composition is described comprising at least one low Tg (meth)acrylic polymer, and at least one silsesquioxane polymer crosslinker comprising a plurality of ethylenically unsaturated groups. The low Tg (meth)acrylic polymer typically has a Tg no greater than 10° C. In some embodiments, the low Tg (meth)acrylic polymer comprises at least 50, 55, 60, 65, or 70 wt-% of polymerized units derived from low Tg ethylenically unsaturated monomer(s). The low Tg ethylenically unsaturated monomer(s) is typically an alkyl (meth)acrylate comprising 4 to 20 carbon atoms. Also described are pressure sensitive adhesive articles and methods of preparing such articles.
