    Abstract: PROCESS FOR COVERING PANE GLASS EDGES USING ELASTIC POLYISOCYANATE POLYADDITION PRODUCTS The invention is a process for coating with an adhesion-improving agent and covering the edges of plate glass, to be fitted to vehicle compartments, with polyurethane, polyurethane-polyurea, or polyurea elastomers. The edges of the plate are coated with one or more layers of an adhesion-improving agent to achieve a good bond between the glass and the elastomer covering. A glass plate is positioned in a mold, the mold closed, and the cavity between the glass plate and mold filled with a reactable mixture of organic polyisocyantes, higher molecular weight compounds having at least two reactive hydrogen atoms, chain extenders and/or crosslinking agents, catalysts, and optionally auxiliaries and/or additives. The reaction mixture is allowed to cure and then the plate glass is removed.

    Abstract: 1. A water-soluble copolymer which comprises, as characteristic monomers, (a) from 80 to 2 % by weight of an ethylenically unsaturated C3 - to C5 -carboxylic acid, acryl-amidodimethylpropanesulfonic acid, vinylsulfonic acid or vinylphosphoric acid, or of an ester of the formula see diagramm : EP0003235,P8,F1 where R is H or -CH3 , n is from 1 to 4 and R**1 and R**2 are alkyls of 1 to 4 carbon atoms, or of mixtures of the said monomers, and (b) from 20 to 98 % by weight of a polymerizable ethylenically unsaturated compound of the formula see diagramm : EP0003235,P9,F2 where R**3 is alkyl of 1 to 20 carbon atoms, R**4 is H or -CH3 , R**5 is H, n is from 2 to 100 and m is from 0 to 50.
