TL;DR: In this paper, the subject composition for lenses of synthetic resin, capable of showing an excellent productivity and good basic characteristics in a well-balanced manner by using a specific curing catalyst, was obtained by including, as a main component, a composite oxide fine particles comprising tin oxide, titanium oxide, and zirconium oxide and a compound of the formula (R 1 is an organic group having a polymerizable reaction group; R 2 is an 1-6C hydrocarbon; X 1 is a hydrolyzable group; and (n) is 0 or 1) and by including
Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition for lenses of synthetic resin, capable of showing an excellent productivity and good basic characteristics in a well- balanced manner by using a specific curing catalyst. SOLUTION: This composition is obtained by including, as a main component, (A) a composite oxide fine particles comprising tin oxide, titanium oxide, and zirconium oxide and (B) a compound of the formula (R 1 is an organic group having a polymerizable reaction group; R 2 is an 1-6C hydrocarbon; X 1 is a hydrolyzable group; and (n) is 0 or 1) and by including, as a curing catalyst, (C) one or more compounds selected from the group consisting of (i) an acetylacetonate having Fe(III), Al(III), Sn(IV), or Ti(IV) as the central metal, (ii) magnesium perchlorate or ammonium perchlorate, (iii) an aliphatic saturated or unsaturated carboxylic acid, or aromatic carboxylic acid or its anhydride, and a mixture thereof, and (D) an acetylacetonate having Li(I), Cu(II), Mn(II), or Mn(III) as the central metal.

Abstract: The results of earlier published Russian and foreign works concerning the use of nanodispersed metal powders in high-energy condensed systems (HECSs) are analyzed and generalized. Modern technological achievements allow one to produce powders of aluminum, boron, and other metals, as well as their alloys and oxides, and make them commercially available. This has resulted in a boom in studies on the possibility of improving HECS characteristics by introducing metal nanopowders in Russia, Europe, Canada, and the United States. The results of some works show that introducing nanopowders of alumina and other metals into rocket propellants, explosives, and pyrotechnic compositions increases their combustion rate and detonation properties. The composition of a double-base propellant (in which the liquid fuel contains 50–150-nm boron nanoparticles and a liquid mixture of hydrogen peroxide and ammonium nitrate is used as an oxidizer) and the composition of a solid rocket propellant based on polybutadiene with end hydroxyl groups, ammonium perchlorate, and 13.0–15.0% boron nanoparticles (which improve the combustion and increase the conversion of the propellant) are of some interest.
