RESIN COMPOSITION, AND PRE-PREG, METAL-CLAD LAMINATE AND PRINTED CIRCUIT BOARD PREPARED USING THE SAME
A resin composition is provided. The resin composition comprises the following components: (A) a halogen-free epoxy resin; (B) a hardener; and (C) a phosphorus-containing phenolic resin of the following formula (I):
##STR00001##
wherein m, n, 1, R.sub.1, and R.sub.2 are as defined in the specification.
FILMS INCLUDING A WATER-SOLUBLE LAYER AND A VAPOR-DEPOSITED ORGANIC COATING
Films including a water-soluble layer and a vapor-deposited organic coating are disclosed. The films can optionally further include a vapor-deposited inorganic layer. The films exhibit enhanced barrier properties.
LEAD-FREE AMMUNITION PROJECTILE
A bullet (ammunition projectile) comprising a branched condensation polymer and a filler, wherein the filler is present in an amount from about 10% to 65% by volume of the branched condensation polymer and filler is described. The bullet may be made by heating a mixture comprised of a branched condensation polymer and a filler comprised of a first and second filler having differing densities and differing particle size distribution to form a molten mixture and injecting the molten mixture into a mold to form the ammunition projectile allowing for the tailoring of the characteristics of the bullet for differing applications.
