  • Dispersion polymers, a process for the preparation thereof, and the use thereof
    Patent number: 5232981
    Abstract: Dispersion polymers composed of a compound or of several compounds of the formula ICH.sub.2 .dbd.CR.sub.1 --CO--NH--(CH.sub.2).sub.n --CH(OR.sub.2)OR.sub.3Iin whichn is 1-6, andR.sub.1 is H or CH.sub.3 and R.sub.2 and R.sub.3 are identical or different and denote --(CH.sub.2).sub.m --CH.sub.3 with m denoting 0-7 or --C(X)(Y)Z with X, Y and Z denoting (CH.sub.2).sub.p CH.sub.3, and p denoting 1-3, where X, Y and Z can be identical or different, and, where appropriate, of another vinyl derivative or of other vinyl derivatives in an aqueous medium, a process for the preparation thereof, and the use thereof for the preparation of conjugates with biologically active substances are described.

  • Dispersion polymers, biologically active dispersion polymers, a process for their preparation, and their use as diagnostic aids
    Patent number: 4921915
    Abstract: Dispersion polymers composed of latex, which have on the particle surface a copolymer composed of monomers having terminal acetals of the formula ICH.sub.2 .dbd.CR.sub.1 --CO--NH--(CH.sub.2).sub.n --CH(OR.sub.2) (OR.sub.3) Iin whichn=1-6;R.sub.1 =H or CH.sub.3, andR.sub.2 and R.sub.3 are identical or different withR.sub.2 and R.sub.3 =--(CH.sub.2).sub.m --CH.sub.3 (m=0-7) orR.sub.2 and R.sub.3 =--CXYZ, X, Y and Z being (CH.sub.2).sub.p --CH.sub.3 and p being 1-3, with X, Y, Z being identical or different,and betaine compounds of the formula IICH.sub.2 .dbd.CR--(CH.sub.2).sub.a --(CO--X).sub.b --Z--(CH.sub.2).sub.c --Y IIwithR=H or CH.sub.3,X=--NH or --0,Y=SO.sub.3.sup.- or COO.sup.- ##STR1## a=0-6, b=0-1,c=1-12,are very suitable for the preparation of biologically active latex reagents which have a particularly high detection sensitivity and stability.
