    摘要: Pressure sensitive adhesives are provided comprising an adhesive copolymer which is a copolymer of a set of monomers comprising: a) 41.0-49.0 weight percent of isobornyl acrylate (IBOA); b) 0.0-4.5 weight percent of one or more basic-functional polar monomers comprising a polymerizable double bond; and c) 46.5-58.9 weight percent of one or more alkyl (meth)acrylate monomers, where the alkyl groups are selected from linear and branched alkyl groups comprising 2-12 carbon atoms and branched alkyl groups comprising 13-20 carbon atoms and wherein weight percentages are weight percent of all monofunctional monomers comprising the adhesive copolymer. In another aspect, the present disclosure provides tapes comprising the pressure sensitive adhesive according to the present disclosure. In some embodiments, the tapes are flexographic plate mounting tapes.

    摘要: Compositions include a compound preparable by reaction of components comprising an optionally crosslinked polyethylenimine and at least one an amine-reactive hydrolyzable organosilane represented by the formula R—Z—SiY3. R represents an amine-reactive group containing 1 to 18 carbon atoms; Z represents a divalent organic group containing 1 to 8 carbon atoms; and each Y independently represents a hydrolyzable group. Methods of using the compositions to make articles, and articles produces thereby are also disclosed. A composition comprising an intimate mixture of a crosslinked polyethylenimine and a polymeric binder material, and a method of making it is also disclosed.
