Abstract: Adhesives comprising: a) 35-85 weight percent of a pressure sensitive adhesive comprising: i) a polymer selected from rubbers and polyacrylate polymers and ii) optionally one or more tackifiers; and dispersed therein b) 15-50 weight percent fire retardant (FR) particles comprising one or more phosphorus-containing compounds selected from organophosphine oxides and organophosphi-nates. In some embodiments, the phosphorus-containing compounds comprise 35-65 weight percent of an organophosphine oxide and 65-35 weight percent of an organophosphinate. The FR particles may have a D50 particle size of 1-120 micrometers, 40-120 micrometers, or 70-120 micrometers. Adhesive films comprising the adhesives described herein may be free-standing adhesive films or adhesive layers comprised in tapes.

Abstract: A composition includes an acrylic polymer, an emulsifier, and water. The acrylic polymer includes monomer units of at least one alkyl acrylate or alkyl methacrylate, wherein alkyl has at least 8 carbon atoms. Not more than one percent by weight of monomer units include a carboxylic acid, sulfonic acid, or phosphonic acid, based on the total weight of monomer units in the acrylic polymer. The composition is an emulsion of the acrylic polymer in water. The composition is a spray adhesive composition and/or coagulates upon being subjected to shear forces. A process for making the composition and a method for making a bonded article using the composition are also described.
