摘要： A filament article containing a curable composition is provided. The filament article has a first part containing an epoxy resin and a second part containing a polyamine having at least two secondary or primary amino groups. The first part is surrounded by a sheath and a second part surrounded by a sheath. Either 1) the first part surrounded by the sheath and the second part surrounded by the sheath are each a separate filament or 2) the first part surrounded by the sheath and the second part surrounded by the sheath combine to form a composite filament. The curable filament article can be used to form a cured composition having structural bonding performance.

摘要： A cationic copolymer comprises the divalent monomer units: wherein: each Ar1 independently represents phenylene; each L independently represents a direct bond or wherein each R1 independently represents an alkyl group having 1 to 4 carbon atoms, and each R2 independently represents an alkylene group having from 1 to 6 carbon atoms, and each Z− represents a non-interfering anion; each Ar2 independently represents an optionally substituted divalent aryl ring, with the proviso that if L represents a direct bond, then Ar2 represents an optionally substituted cationic divalent aryl ring accompanied by Z; each R3 independently represents H or an alkyl group having 1 to 6 carbon atoms; and each D independently represents a direct bond or Ar2, wherein adjacent D and L are not both direct bonds, and wherein if L is a direct bond, then D is Ar2. The cationic copolymer can be free-radially cured and used in a membrane.

摘要： Cationic polymers are provided that comprise monomeric units of Formula (V). (V) Each asterisk (*) indicates an attachment position to another monomeric unit; R is hydrogen or methyl; each R2 is each independently an alkyl, aryl, or a combination thereof; L is a linking group comprising an alkylene group; and +R3 is a cationic nitrogen-containing group free of any N—H bonds. Membranes formed from said cationic polymers, devices including such membranes, and methods of making such cationic polymers are also provided.

摘要： A core-sheath filament is provided that includes a curable composition. The curable composition contains an epoxy resin and a photoacid generator. Methods of making the core-sheath filament and methods of using the core-sheath filament for printing and bonding are provided. The core-sheath filaments can be used to form a cured composition having structural bonding performance.
