The invention relates to the use, for coating or sealing panes of laminated safety glass, of polymers of: A) 30 to 90 wt.% ethylene; B) 0 to 10 wt.% of other .alpha.-olefines with 2 to 12 C atoms which may also carry halogen atoms; C) 3 to 40 wt.% of one or more acrylic or methacrylic acid esters in which the ester radical consists of C1 to C20 alkyl, C5 to C18 cycloalkyl or C7 to C18 aralkyl, in which said ester radical may also bear halogen atoms; D) 7 to 30 wt.% acrylic acid and/or methacrylic acid; and E) 0 to 10 wt.% of further copolymerisable monomers.
On utilise pour enduire ou sceller des vitres en verre de sécurité feuilleté des polymères constitués de: (A) 30 à 90 % en poids d'éthylène; (B) 0 à 10 % en poids d'autres .alpha.-oléfines de 2 à 12 atomes de carbones et qui peuvent également porter des atomes d'halogène; (C) 3 à 40 % en poids d'un ou de plusieurs esters d'acide acrylique ou méthacrylique, le reste ester étant constitué d'alkyle C¿1?-C¿20?, de cycloalkyle C¿5?-C¿18? ou d'aralkyle C¿7?-C¿18? et pouvant porter des atomes d'halogène; (D) 7 à 30 % en poids d'acide acrylique et/ou méthacrylique; et (E) 0 à 10 % en poids d'autres monomères copolymérisables.
