Versuchsvorschrift
45 g. of an ethylene/n-butylacrylate/glycidyl methacrylate containing 4 wt. % GMA and 30 weight percent nBA and having a melt index of 1000 was reacted with 3.3 g. of N-cyclohexylaminopropyl trimethoxysilane in a Brabender mixer at 160° C. for 10 min. Rotor speed was 100 rpm. This represents a stoichiometric balance of aminosilane to the glycidyl moiety. The MI of the grafted product was 1098. This is above that of the direct copolymer which suggests that little or no crosslinking occurred during the preparation of the grafted copolymer.
