The films comprise a combination of at least one elastomeric styrenic block copolymer which is optionally functionalized with functional groups different from sulfonic acid or sulfonate ester functional groups, and at least one sulfonated block copolymer. Films comprising the optionally functionalized block copolymer(s) and the additional sulfonated block copolymer(s) are elastic and are moisture-vapor permeable, and thus useful as coatings in breathable clothing and footwear, industrial workwear including cleanroom coveralls, in medical applications such as wound dressings and protective clothing, for bed sheets and mattress or seat covers, and other non-apparel applications.

  • Patent number: 9056925
    Abstract: A process for producing a modified conjugated diene based polymer includes a step (a) of reacting a silicon compound with a conjugated diene based polymer having an active end so that the reaction takes place at the active end, the silicon compound having a protected primary amino group in the molecule thereof and a silicon atom to which a hydrocarbyloxy group and a reactive group are bonded, to thereby modify the active end, and a step (b) of performing condensation reaction, in the presence of a titanium compound serving as a titanium-based condensation-accelerating agent. A rubber composition contains the modified diene polymer, and a tire is produced from the rubber composition.
