摘要：Polyethylene with an average molecular weight of 500 to 10,000 is disclosedhaving one or several laterally bound group(s) of the formula ##STR1## wherein R.sup.1and R.sup.2 are the same or different and represent a lower alkyl group with 1 to 4carbon atoms, R.sup.3 is a bivalent alkylene residue and n is 2 or 3. A method for thepreparation of the modified polyethylene is also disclosed. The polyethylene, preferablyin the form of an aqueous dispersion, is applied to glass surfaces, especially the externalsurface 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 repeatedaction of hot aqueous washing liquors and retain their smoothness. The glass containers,provided with the protective layers, may be labelled in the usual manner.
