    摘要: Describes a process for controlling the polymerization and cross-linked density of electrophoretic gel products useful for separation of bioorganic molecules, which process does not use initiators common to processes of the art. Electron beam polymerized gels afford the desired advantages of being ultra thin and having a high electrophoretic resolution with programmable porosity profiles.

    摘要: Novel melt-spun elastomeric fibers and methods for their preparation. Embodiments are provided in which fibers are melt-spun from a melt-spinnable elastomeric polymer comprising a diisocyanate-capped polyol prepolymer which is chain-extended with an aromatic dihydroxy compound. Also provided are melt-spinnable elastomeric polymers and prepolymers therefor. The fibers may be knit or woven into textile articles including, inter alia, hosiery and pantyhose.

    摘要: Sharper edges are obtained in silver halide wash-off films for tanning development when from 5 to 60% of the unhardened gelatin binder in one or more layers is replaced with a synthetic amphoteric polymer consisting essentially of at least one of each of three constituents: (a) carboxylic acid, (b) alkyl primary amine, and (c) secondary and/or tertiary amine, the amphoteric polymer having an isoelectric point of from 4 to 8.
