Abstract: WATER-INSOLUBLE PARTICLE AND IMMUNOREACTIVE REAGENT, ANALYTICAL ELEMENTS AND METHODS OF USE            Abstract of the Disclosure A water-insoluble polymeric particle has an inner core comprising a detectable tracer material distributed in a first polymer for which the tracer material has a high affinity.  This first polymer has a glass transition temperature (Tg1) less than about 100°C.  The particle also has an outer shell comprising a second polymer for which the tracer material has substantially less affinity relative to said first polymer.  This second polymer has a glass transition temperature (Tg2) which is greater than or equal to the term [Tg1-10°C].  It also contains groups which are either reactive with free amino or sulfhydryl groups of an immunoreactive species or which can be activated for reaction with such groups.  Such a species can be covalently attached to this particle to form an immunoreactive reagent which is useful in analytical elements and various analyti-cal methods including immunological methods, for ex-ample, agglutination assays.

Abstract: ABSTRACT     Expandable and expanded plastic materials having a majority of alkyl acrylate monomeric repeat units are disclosed.  These materials when expanded have a volume expansion of at least 60 and maintain that volume expansion for a period of at least 30 minutes under expansion conditions after reaching the volume expansion of 60.  Expandable and expanded plastic materials having a majority of alkyl acrylate monomeric repeat units and an inhibitor for the monomer(s) and a crosslinker incorporated into the plastic material upon monomer polymerization are also disclosed.  Also disclosed are expandable and expanded plastic materials having a majority of alkyl acrylate monomeric repeat units with blowing agents of 2,2-dimethylbutane, 2,3-dimethylbutane or mixtures of one or both with 1-chloro-1,1-difluoroethane or mixtures of at least 30 percent of one or both with other volatile blowing agents.       These specific types of formed pattern  and core assemblies, wholly or partially formed from the destructible expanded closed-cell cellular plastic materials of the present invention have a decreased tendency to form nonvolatile residue during the casting of metals such as iron.  Superior castings are thereby obtained without resort to uneconomic casting methods.       Further disclosed is a method of casting metal castings using the disclosed expanded plastic material articles (Lost Foam or Evaporative Pattern Casting). The disclosed expanded plastic material articles are especially preferred for metal castings having a final carbon percentage of 1.8 weight percent or less in the final casting.

Abstract: ABSTRACT    High grade quaternary ammonium salts represented by the following General Formula II:                      II            (in which R1 represents a hydrogen atom or a methyl group; R2 and R3 independently represents an alkyl group containing 1 to 4 carbon atoms; A represents an oxygen atom or an -NH- group; B represents an alkylene group containing 1 to 4 carbon atoms; R4 represents an alkyl group or a benzyl group; and X- represents a halogen anion) can be produced by reacting a cationic vinyl monomer represented by the following General Formula I:                    (in which R1, R2, R3, A and B have the same meanings as defined above) with an alkyl halide or an aralkyl halide in a medium consisting of a particular mixture of water and an aprotic organic solvent under a condition where the concentration of oxygen dissolved in the reaction system is lower than 1.8 ppm but not less than 0.3 ppm. The reaction proceeds quite smoothly, without forming deposition of quaternary ammonium salts produced by the reaction. The overheating of the reaction system, which is a cause for the generation of gelation-causing substances and polymerization inhibitors, can be prevented effectively since the reaction mixture can be smoothly stirred and hence the generated heat can be efficiently removed therefrom. The process therefore enables to produce on a commercial scale aqueous solutions of unsaturated quaternary ammonium salts of very high quality which can be used as a raw material for producing cationic polymers of high molecular weight.
