Verfahren zur Herstellung mehrlagiger Stoffe unter Verwendung eines Haftvermittlers

摘要

The use of a copolymer (I) as a bonding agent between first and second materials (A and B) is claimed. Material (A) contains not more than 70 wt% 2-4C olefin(s) in polymerised form. Material (B) contains at least 70 wt% 2-4C olefin(s) in polymerised form. (I) is a copolymer of: (a) 70-90 wt% 2-4C olefin(s); and (b) 10-30 wt% alpha , beta -monoethylenically unsatd. 3-8C (pref. 3-5C) monocarboxylic acid(s) and/or alpha , beta -monoethylenically unsatd. 4-8C (pref. 4-5C) dicarboxylic acid(s) and/or anhydrides of the mono- and dicarboxylic acids. Also claimed are: (i) a process for the prodn. of multilayer materials by coating material (A) with (I) and contacting the treated surface with (B); and (ii) floor covering contg. a layer of (A) and a layer of (B) bonded together with (I)
