Abstract:

A film having a width of at least about one foot as defined by the cross machine direction thereof and a substantially uniform average thickness of less than about 10 mils is formed of a crosslinkable thermoplastic olefin polymer, a crosslinking agent, and preferably a flame retardant. The film can be combined with a suitable substrate to form a prepreg or coated substrate, and the prepreg or coated substrate can be subsequently treated under conditions to crosslink the olefin polymer and to form a rigid composite structure. The composite structure is particularly useful for printed circuit board applications.
