A method for controlling power of a shared forward link data channel for multicasting in a mobile communication system. The modules are connected to the data bus and each one of the modules is in communication with each one of the other modules via at least one control line such that each one of the modules is capable of receiving control signals generated by each other module. The improvement resides in the inclusion of at least one boron-containing compound in one or both of the first and second polymeric layers in an amount sufficient to improve the interlayer adhesion between the first and second polymeric layers.
