Abstract: A copolymer composition including a copolymer having repeat units of structural formula I: where X is selected from —CH2—, —CH2—CH2— and O; m is an integer from 0 to 5; and each occurrence of R1-R4 are independently selected from H; C1 to C25 linear, branched, and cyclic alkyl, aryl, aralkyl, alkaryl, alkenyl and alkynyl that can include one or more hetero atoms selected from O, N, and Si; a group that contains an epoxy functionality; —(CH2)nC(O)OR5; —(CH2)nC(O)OR6; —(CH2)nOR6; —(CH2)nOC(O)R6; —(CH2)nC(O)R6; —(CH2)nOC(O)OR6; and any combination of two of R1, R2, R3, and R4 linked together by a linking group. A portion of the repeat units having structural formula I contain at least one epoxy functional pendant group. The copolymer composition can be included with a material that photonically forms a catalyst in a photodefinable dielectric composition, which can be used to form a photodefinable layer on a substrate.

Abstract: A device useful for oral drug delivery device consisting of: (a) a capsule, tablet or pill designed to disperse in the gastrointestinal system; (b) an RFID tag positioned in the capsule, tablet or pill, the RFID tag comprising an antenna; (c) an object selected from the group consisting of a magnet, a ferromagnetic object, a ferrite object and an electromagnetic shielding object positioned within, over or adjacent the antenna of the RFID tag to alter the antenna characteristics of the RFID tag so that if the RFID tag is interrogated before the capsule, tablet or pill disperses in the gastrointestinal system, the response of the RFID tag is sufficiently altered or attenuated to determine that the capsule, tablet or pill has not dispersed in the gastrointestinal system and so that if the RFID tag is interrogated after the capsule, tablet or pill has dispersed in the gastrointestinal system, the object separates from the RFID tag so that the response of the RFID tag is sufficiently detectable to determine that t
