Benzyl Chloride → HCID 21946369, compound

Participants

Reaction Steps

Example 1 was repeated except that the copper foil was pretreated with a silane solution prepared as follows. 8.8 g. of N-2-amino-ethyl-3-aminopropyltrimethoxysilane (a product of Petrarch Systems, Inc.) and 5.0 g. of benzyl chloride were charged in a reaction vessel to produce 3-(N-Benzyl-2-aminoethylamino)-propyltrimethoxysilane hydrochloride. A 1% solution of this silane in methanol was prepared, the copper foil dipped therein for 30 minutes followed by air drying and a 5-minute bake at 105° C. The copper foil was laminated to similar prepregs (2-ply, 6.12 g, 59.8% polymer uptake) as described in Example 1 and cured at 180° to 220° C. for 30 minutes under psi pressure. A 2-ply 3"×6" laminate was obtained.
