    摘要: Disclosed are four gel compositions that have improved properties over the prior art. These gels include elastosols, solid rubbery gels, UV cured gels and chemically cured gels. The gels are formed from selectively hydrogenated styrene/diene block copolymers, unhydrogenated styrene/diene block copolymers, and selectively hydrogenated styrene/diene block copolymers that have been maleated.

    摘要: The present invention relates to photocurable compositions for use in flexographic printing plates comprising selectively hydrogenated block copolymers of conjugated dienes and monoalkenyl arenes and flexographic printing plates made from the same. The block copolymers, either linear or radial, have terminal blocks of unsaturated conjugated diene. The block copolymer is further comprised of monoalkenyl arene blocks and hydrogenated conjugated diene blocks. The compositions exhibit exceptional improvement in degree of cure over comparative selectively hydrogenated block copolymers.

    摘要: Pressure sensitive structural adhesive and sealant compositions comprising: (a) a polymer system comprising from 95 to 15 percent by weight of a telechelic polymer and from 5 to 85 percent by weight of a heterotelechelic polymer wherein at least one of the functionalities thereon is the same as the functionality on the telechelic polymer, and (b) a dual curing system wherein one element of the curing system cures the telechelic polymer and the common functionality on the heterotelechelic polymer and the other element cures the functionality on the heterotelechelic polymer but does not cure under the conditions required to cure the telechelic polymer to form a structural adhesive or sealant composition. In a preferred embodiment, the polymer system is comprised of a hydroxyl functional telechelic diol or polyol polymer and the heterotelechelic polymer is a monohydroxylated polydiene polymer which also has epoxidized olefin functionality. The dual curing system preferably is comprised of an isocyanate curing agent to cure through the hydroxyl groups at ambient temperatures to form a pressure sensitive adhesive or sealant and an amino resin to cure through the epoxy functionality upon baking to form a structural adhesive or sealant.
