    摘要： Oxymethylene copolymers having a high proportion of terminal alkyl ether groups and having terminal hydroxyalkylene groups are described. These polymers are distinguished by high thermal stability and high hot water resistance.Furthermore, a process for the preparation of oxymethylene copolymers is described in which the polymerization of at least one monomer forming —CH2—O— units is effected in the presence of at least one acetal of formaldehyde and of at least one initiator of cationic polymerization and the initiator of cationic polymerization is used in an amount of less than or equal to 10−4 mol %, based on the amount of the monomers present at the beginning of the polymerization and forming —CH2—O— units, in which starting materials of the polymerization are used such that the content of water and formic acid at the beginning of the polymerization is less than or equal to 40 ppm, and in which the initiator and/or the active polymer chains are deactivated by treatment of the prepared polymer with a base-containing protic solvent.

    摘要： Suspension polymerization of acrolein type compounds in the presence of appropriate surfactants results in the formation of microspheres in size ranging from 0.03 to 80 microns. Fluorescent and magnetic microspheres are obtained by carrying out the same polymerization in the presence of appropriate fluorochromic or ferrofluidic compounds, respectively. Hybrido-polyacrolein microspheres are obtained by grafting one type of such microspheres on another type. Immunomicrospheres were formed by binding covalently at physiological pH appropriate proteins to the microspheres. The immunomicrospheres can be used for various biological applications, such as specific markers for labeling cell surface receptors, for cell separation, for diagnostic purposes, etc.

    摘要： Homopolymeric polyaldehyde microspheres can be prepared in yields of up to about 90% by preparing an aqueous solution consisting essentially of a suitable concentration of an .alpha.,.beta.-ethylenically unsaturated aldehyde and a suitable concentration of an appropriate surfactant under suitable conditions such that the surfactant has a net electrostatic charge. The solution, which may also contain a ferrofluidic material, fluorescent dye or additional solvent, is then irradiated under an inert atmosphere with a sufficient dose of .gamma.-radiation to effect polymerization and the monodisperse homopolymeric polyaldehyde microspheres so produced are recovered. Copolymeric polyaldehyde microspheres can be prepared by adding to the solution a suitable concentration of a copolymerizable comonomer before initiating polymerization.Monodisperse homopolymeric or copolymeric polyaldehyde microspheres useful for affinity chromatography, cell labeling, cell separation and diagnostic purposes can thus be prepared in significantly higher yield than was previously obtainable.
