    摘要: This specification discloses that certain polychlorinated or polybrominated aromatic hydrocarbon compounds can be incorporated in thermosetting polymer compositions to make the thermosetting compositions flame retardant without injuring the desirable physical and electrical properties of the thermosetting compositions when in the thermoset state. These polyhalogenated aromatic hydrocarbons are apparently caused to reset into the thermosetting composition, provided there is a minimum of 1 mol of a polyunsaturated monomer containing carbon to carbon unsaturation for each 3 mols of polychlorinated aromatic hydrocarbons. The thermosetting compositions generally contain a polyunsaturated monomer, a polyunsaturated polymer with carbon to carbon double bond unsaturation or a polyphenylene ether polymer which may be used in place of some or all of the polyunsaturated polymer, and a polyhalogenated aromatic hydrocarbon, containing at least 50% by weight combined chlorine or bromine and whose molecular weight is greater than 200. These thermosetting compositions can be heat cured or thermoset by a free radical initiator at a temperature of at least 130.degree. C., and can contain pigments, reinforcing fibers, release agents, coupling agents, and other incidental amounts of additives commonly used in thermosetting resin compositions.

    摘要: Apparatus and methods for combining multiple modes and methods of optical detection, postprocessing, and/or feedback loops in bioanalytical measurements. The methods may include (1) positioning a composition at an examination site in a multi-mode instrument; (2) detecting light transmitted form the composition using the multi-mode instrument in a first optical measurement mode; (3) detecting light transmitted from the composition using the multi-mode instrument in a second optical measurement mode, the second mode being different than the first mode; and (4) computing a quantity related to a property of the composition using the light detected in at least one of the optical measurement modes. These steps may be performed on one or more samples, simultaneously and/or sequentially. The quantity may relate to photoluminescence, chemiluminescence, absorption, and/or scattering, among others.
