Abstract:
A process is provided for the production of stable aqueous polymer dispersions by subjecting vinyl monomers to radical emulsion polymerization in the presence of a stable aqueous dispersion of a high molecular weight polyurethane containing anionic groups.
Abstract:
High molecular weight cationic copolymers of (meth)acrylamide and tertiary or quaternary aminoalkyl(meth)acrylates are produced by copolymerization of said monomers in the presence of a redox system of a water-soluble percompound and of a compound containing at least one primary amine group or a water-soluble salt thereof in aqueous oxygen-free solution at a temperature of from 10* to 40*C.
Abstract:
CHLOROMETHYL ESTERS OF A B-UNSATURATED CARBOXYLIC ACIDS ARE PRODUCED BY REACTING A B-UNSATURATED CARBOXYLIC ACID CHLORIDE WITH FORMALDEHYDE OR WITH A FORMALDEHYDE DONOR IN THE PRESENCE OF A CATALYTIC QUANTITY OF FERRIC CHLORIDE OR STANNIC CHLORIDE.
Abstract:
Cross-linked homopolymers and copolymers based on Alpha , Beta -unsaturated acylaminomethylene carbamic acid esters, their utility as binders for pigments, fleeces and textile materials, as paper auxiliaries and as coating agents and process of producing the same by radical polymerization.
