Abstract: A garment for wearing while In-Line Skating comprised of a pair of loose fitting outer shorts (12) and form fitting inner shorts (14). Both shorts having padded portions to absorb the impact of a fall when landing on the hips, buttocks and or coccyx. The impact protection being provided by a fixed pad (46) in the inner shorts (14) and by removable pads (32) which fit securely into pockets on the rear portion of the outer shorts (12). The outer shorts (12) also providing abrasion and cut protection by utilizing highly abrasion resistant fibers in the rear section.

Abstract: Pentadienyl ether terminated polyethers and maleimidomethyl carbonate terated polyethers are selectively combined via a Diels-Alder reaction at room temperature. The resulting aliphatic copolyethers are characterized by having at least two chemically combined N(1)-oxycarbonyloxymethyl-4-oxymethyltetrahydrophthalimido groups interposed between polyether radicals within the copolymer chain. The aliphatic polyether precursors terminated with pentadienyl ether groups are synthesized by reacting an aliphatic hydroxy terminated polyether with a metal alkoxide to form at least the bis alkoxide derivative. The alkoxide derivative is then reacted with a halogen substituted pentadiene yielding the bis or tris pentadiene ether terminated polyether for use in the copolymer synthesis.

Abstract: Aliphatic polyethers having at least two N-methylmaleimide groups chemica joined thereto by a carbonate linkage are provided and a method for making such compounds. The hydroxy-terminated aliphatic polyether, such as polypropylene glycol, is initially reacted with carbonyl chloride to form the chloroformate. The polyether chloroformate derivative is then reacted with N-hydroxymethylmaleimide yielding the bis or tris(maleimidomethyl)carbonate of said polyether.

Abstract: Free radical cure of the bismaleimide of dimer diamine is accomplished with ydroperoxides promoted with a vanadium trineodecanoate/N,N-dimethyl-p-toluidine mixture to form a hard polymer.

Abstract: Hydroxy terminated polybutadiene is reacted with naphthyl-potassium and 1omo-2,4-pentadiene in successive steps to form a bis(1,3-pentadienyl ether) derivative. Then the bismaleimide of dimer diamine is added to the polybutadiene derivative whereby a room temperature cure to an elastomer is achieved.

Abstract: Polymeric binders for plastic bonded explosives. The binders are prepared om polyfunctional ortho-nitrophenols and polyisocyanates. The binders will reversibly dissociate when subjected to temperatures the range of from 100.degree. to 150.degree. C.

Abstract: Hydroxy terminated polybutadiene is reacted with naphtyl-potassium and 1-mo-2,4-pentadiene in successive steps to form a bis(1,3-pentadienyl ether) derivative. Then the bismaleimide of dimer diamine is added to the polybutadiene derivative whereby a room temperature cure to an elastomer is achieved.

Abstract: A stripline board material of hollow glass microspheres chemically bonded to a coating material and physically held in a polymeric matrix, preferably homo- or co-polymers of ethylene, propylene and/or styrene. The coating material is a difunctional silane with one functional group bound to the glass and the other bound either to the matrix or to a copolymer of a structure similar to the structure of the matrix. In the latter case, the sphere-silane-copolymer forms an intimate mixture with the matrix.

Abstract: The bismaleimide of dimer diamine is synthesized using N,N'-dicyclohexylcodiimide and 1-hydroxybenzotriazole.
