摘要
Polyethylene with an average molecular weight of 500 to 10,000 is disclosed having one or several laterally bound group(s) of the formula IMAGE I wherein R1 and R2 are the same or different and represent a lower alkyl group with 1 to 4 carbon atoms, R3 is a bivalent alkylene residue and n is 2 or 3. A method for the preparation of the modified polyethylene is also disclosed. The polyethylene, preferably in the form of an aqueous dispersion, is applied to glass surfaces, especially the external surface of glass containers. The modified polyethylene is especially suitable for the so-called cold-end finishing of glass. The protective layers are resistant to the repeated action of hot aqueous washing liquors and retain their smoothness. The glass containers, provided with the protective layers, may be labelled in the usual manner.
