    摘要： A chemically defined polymeric carrier comprising a series of α-amino acids in any combination containing side chains to which diagnostic/therapeutic and chelating agents can be covalently joined through cleavable linkers either directly or covalently joined through cleavable linkers after chemical modification of the side chains. Hydrazone, disulfide, and ester linkages in any combination can be present in the polymeric carrier between the side chains of the α-amino acids and the agents. The presence of a particular covalent linkage between the side chain and the agent in the carrier is determined by the functional group present in the side chain of the α-amino acid and the functional group present in the agent. The α-amino acids with side chains to which agents do not covalently join can function as spacers to minimize interaction between bulky molecules attached to the polymeric carrier. In addition, those α-amino acids with charge or hydrophilic side chains to which agents do not covalently join can provide increased solubility to the polymeric carrier.

    摘要： A method of preparing an α-cyanoacrylate ester of a desired alcohol includes the steps of
       preparing a compound which is an α-selenoaryl-α-cyanopropionate ester of the desired alcohol,
       oxidizing said α-selenoaryl-α-cyanopropionate ester to the corresponding selenoxide,
       eliminating arylselenic acid from the selenoxide to produce said α-cyanoacrylate ester, and
       separating said α-cyanoacrylate ester from the selenic acid.
    At temperatures of about 0°C or higher, the elimination step occurs concurrently with the oxidizing step using a peroxide or ozone oxidizing agent. The desired cyanoacrylate ester is obtained in good yield and very high purity. The method can be used to prepare difficult to synthesize plural functional cyanoacrylate monomers and mono-cyanoacrylate monomers regardless of alcohol chain length.

    摘要： Compositions comprising:

    A) A mixture of acrylate functional prepolymers in the total amount of between about 50% and 80% by weight of the composition, said prepolymer mixture comprising a first prepolymer which is a urethane diacrylate resin, suitably a polyether urethane diacrylate, having a viscosity of at least 500,000 mPa.sec at 25°C in an amount of between 10 and 40% by weight of the composition, and a second multi-acrylate prepolymer having a viscosity of between about 500 and 50,000 mPa.sec in an amount of at least 15 % by weight of the composition;
    B) A monoacrylate diluent monomer selected from the group consisting of isobornyl acrylate, β-carboxyethyl acrylate and mixtures thereof in an amount of at least 5 % by weight of the composition; and,
    C) An effective amount for cure initiation of a free radical initiator, the composition having a viscosity of less than 10,000 mPa.sec at 25°C, give unusual self-toughened cured properties. Such compositions, where the free radical initiator is a free radical photoinitiator, are particularly useful in rapid prototyping applications where the requirement for low viscosity and optical clarity of the liquid formulation has heretofore limited use of the formulations to ones giving undesirably brittle or soft properties.
