摘要： Methods of forming an adhesive composition including the steps of (a) combining a non-deaerated mixture comprising at least one free radically (co)polymerizable ethylenically-unsaturated material with a sealable packaging, wherein the packaging contains the non-deaerated mixture; (b) sealing the non-deaerated mixture in the packaging to form a sealed packaging; and (c) exposing the non-deaerated mixture in the sealed packaging to a source of ionizing radiation for a time sufficient to initiate (co)polymerization of at least a portion of the at least one free radically (co)polymerizable ethylenically-unsaturated material to form an adhesive composition in the sealed packaging. The (co)polymerization takes place essentially non-adiabatically. At least a portion of the packaging is meltable and mixable with the adhesive composition so as to provide a flowable coatable adhesive composition when the sealed packaging containing the adhesive composition is heated to a temperature sufficient to melt at least a portion of the packaging.

摘要： The present disclosure provides a method of separating (e.g., purifying, clarifying, etc.) a virus from a composition. The method includes a) obtaining a composition containing a virus and at least one of deoxyribonucleic acid (DNA) or host cell proteins (HCP); b) passing at least a portion of the composition through a copolymer-grafted nonwoven substrate to provide a filtrate; and c) collecting the filtrate, which contains 50% or greater of an amount of the virus present in the composition. The composition has a pH of 6 to 8.5 and a conductivity of 4 or more milliSiemens per centimeter. The grafted copolymer includes interpolymerized monomer units of (i) a quaternary ammonium containing monomer or salt thereof; (ii) a hydrophilic amide containing monomer; and (iii) an epoxy containing monomer. The copolymer-grafted nonwoven substrate assists in retaining impurities such as DNA and HCP while certain negatively-charged viruses pass through the substrate.
