摘要:
Hydrophilic compositions are described, which are prepared from a first component oligomer containing pendent hydrophilic groups and pendent reactive functional groups capable of reaction at effective rates (at normal processing temperatures), with a co-reactive second component possessing functionality that is complementary to that of the first oligomer. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.
摘要:
The present invention provides crosslinkable compositions useful in the preparation of hydrophilic gels, and are prepared from oligomers having pendent hydrophilic, poly(alkylene oxide) groups, pendent photoinitiator groups, and optionally polymerizable functional groups, and crosslinked by polyfunctional poly(alkylene oxides).

摘要:
This invention relates to polymeric compositions that are processible and may be photochemically cured to produce crosslinked compositions useful in coating, sealants and adhesive applications. The crosslinkable composition comprises a first component having a plurality of pendent, free-radically polymerizable functional groups; a polymeric photoinitiator, and a residual content of less than 2%. The composition is melt processable at temperatures of less than or equal to 100° C.
摘要:
A process for preparing a polarizer is described whereby a pre-polarizing article comprising an oriented, vinylalcohol polymer film layer, and an acid donor layer comprising a thermal acid generator, is exposed to radiant energy at a temperature sufficient to effect a partial dehydration of the vinylalcohol polymer to a vinylalcohol/poly(acetylene) copolymer.
