Abstract: Resinous articles, especially polycarbonate articles, coated with an abrasion-resistant surface coating such as a silicone hardcoat, contain a primer coat between the article and the surface coating, said primer coat being a copolymer of a monomer mixture including an ethylenically unsaturated monomer having an ultraviolet degradation inhibiting moiety, preferably a 4-(2-hydroxybenzophenone)oxy moiety. The articles are characterized by improved hardcoat adhesion and resistance to discoloration and ultraviolet degradation.

Abstract: Compositions comprising 1,2-alkanediol diacrylate monomers may be polymerized to form polymers useful as dielectrics for capacitors. Said dielectrics are characterized by low dissipation factor and low capacitance change over a wide range of temperatures.

Abstract: Novel polymerizable 3-aroyloxyphenyl carbamates such as 3-benzoyloxyphenyl 2-methacryloxyethylcarbamate form addition polymers which are useful as surface coatings for resinous (especially polycarbonate) articles. The coatings protect the resinous articles against discoloration as the result of ultraviolet radiation-induced degradation and also may serve as primers for abrasion-resistant coatings such as silicone hardcoats.

Abstract: Compositions comprising polyfunctional acrylate monomers of the formula ##STR1## wherein R.sup.1 is an aliphatic or alicyclic radical having about 20-40 carbon atoms, R.sup.2 is hydrogen or methyl, and n is from 2 to 4, at least about 40% of said monomers containing alicyclic R.sup.1 moieties, may be polymerized to form polymers useful as dielectrics for capacitors. Illustrative polyfunctional acrylates are those prepared from a diol which is the reduction product of linoleic acid dimer, or from condensation products of fatty acids such as linoleic acid with such materials as acrylic acid.

Abstract: Compositions comprising mixed acrylates and propionates, or the like, of polyhydroxy compounds of the formula R.sup.1 (OH).sub.n, wherein R.sup.1 is an aliphatic or alicyclic radical having about 1-40 carbon atoms and n is from 2 to 4, may be polymerized to form polymers useful as dielectrics for capacitors. Said capacitors are characterized by low dissipation factors at both high and low temperatures.

Abstract: Novel capacitors comprise two electrodes and, as a dielectric member, a polymer of at least one polyfunctional acrylate of the formula ##STR1## wherein R.sup.1 is an aliphatic, alicyclic or mixed aliphatic-alicyclic radical having about 10-40 carbon atoms which is preferably branched, R.sup.2 is hydrogen or methyl, and n is from 2 to 4. Said capacitors are characterized by a low dissipation factor.
