    摘要: A water activated adhesive system is described that is particularly suited for applying non-paper polymeric labels to surfaces which have low moisture permeability. The adhesive system is characterized by a dry non-tacky surface that becomes tacky in less than one second when contacted with a water-based activator. While it is a water activated adhesive, it is also characterized after aging bonded to a substrate by resistance to adhesive failure during 72 hours of immersion in ice/water mixture. The adhesive is beneficial to allow use of existing paper labeling equipment with polymeric labels.

    摘要: Aldehyde-telechelic polyisobutylenes free of other end groups such as alcohols, olefins, etc., are made by the hydroformylation of polyisobutylene having one or more olefinic end groups in the presence of a rhodium catalyst in combination with an organic phosphorus ligand. Very high conversions of olefin to aldehyde are obtained. Depending upon the number of aldehyde end groups per macromolecule, the telechelic polyisobutylene polymers can be utilized as precursors to form various types of block copolymers, e.g., AB, ABA, or radial block copolymers, with other polymers such as polyurethanes, polyesters, polyamines, and the like.
