Abstract: Flame-resistant molding compositions are prepared by adding at least one substance selected from the class consisting of (a) oxides or hydroxides of the rare earth metals, (b) graphite, or (c) precious metals or their compounds or complexes and mixtures of (a), (b) or (c) to a composition containing mixtures of organic polymers other than diorganopolysiloxanes and diorganopolysiloxanes. Although it is not essential, silicon dioxide having a surface area of at least 50 m.sup.2 /g and crosslinking agents may be incorporated in these molding compositions.

Abstract: Polyacetal molding materials which contain, as a stabilizer, from 0.1 to 10% by weight of a melamine resin, the latter being a melamine-formaldehyde condensate, having a mean degree of polymerization of from 1.2 to 6.0 and a melamine:formaldehyde ratio of from 1:2 to 1:5.5, which has been partially etherified with a C.sub.1 -C.sub.4 -alkanol so that the ratio melamine:ether radicals is from 1:1.5 to 1:5.0 and the ratio melamine:free methylol groups is from 1:0.5 to 1:3. The molding materials can be converted to moldings which can be used industrially at elevated ambient temperatures.

Abstract: Pigmented thermosetting organic solvent solution coating compositions are disclosed which cure to provide improved weather resistance. These coating compositions contain three resin components, as follows:1- an essentially nonfunctional organic solvent-soluble silicone resin reaction product of a highly branched, low molecular weight hydroxy function polyester with an hydroxy or alkoxy-functional organic polysiloxane, the polysiloxane constituting from 8% to 20% of the three resin components, and the polyester and the polysiloxane being combined in approximately stoichiometric proportions;2- a reactive organic solvent-soluble essentially linear high molecular weight hydroxy functional polyester constituting the balance of the three resin components; and3- from 3% to 15% of the three resin components of a heterocyclic aminoplast resin for curing the reactive polyester.

Abstract: A thermosetting synthetic crosslinking resin containing selected ethers of the reaction product of an isoadipoguanamine mixture and formaldehyde can be incorporated into a variety of coating compositions to provide finishes that are characterized by hardness, flexibility, durability, excellent adhesion, and commercially-acceptable cure temperatures.

Abstract: This invention relates to pressure sensitive adhesive compositions which include an amine terminated polyalkylene oxide neutralized sulfonated thermoplastic polymer, wherein the neutralized sulfonated thermoplastic polymer has about 5 to about 250 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated thermoplastic polymer, dissolved in a nonreactive solvent at a concentration level of about 5 grams to about 25 grams per 100 ml. of nonreactive solvent. To control the end use properties of the solvent-based pressure-sensitive formulations, optionally, tackifying resins can also be incorporated in the solution.

Abstract: Sparingly soluble isoindoline colorants of the formula ##STR1## where R is carbamyl, N-C.sub.1 -C.sub.4 -alkylcarbamyl or N-phenylcarbamyl and Q is a group of the formula ##STR2## where A is 1,3- or 1,4-phenylene and the ring B is 1,2-phenylene, 1,2-naphthylene or 2,3-naphthylene and R has the above means, and where the phenyl radicals in R, A and B independently of one another may be unsubstituted or substituted by groups which do not confer solubility.The colorants I may be used as pigments and for coloring finishes, printing inks and plastics.

Abstract: A sizing composition and method of preparing sized glass fiber strand is provided to produce sized glass fiber strand that has reduced tackiness. The sizing composition has a low molecular weight liquid polymer selected from the group consisting of styrene-butadiene copolymer, acrylonitrile-butadiene copolymer or hydroxy or carboxy derivatives of said copolymers, epoxy resins, polyester resins, or polyurethane resins that are free radically curable; and a free radical precurser selected from the group consisting of peroxides, hydroperoxides in an amount in the range of about 0.2 to 5 parts per hundred parts of liquid polymer in said sizing composition; or the said liquid polymer that can be treated with radiation to produce an equivalent amount of free radicals.

Abstract: The varnish comprises a phenolated naphthalene formaldehyde resin having a molecular weight from 350 to 500 and a combined phenol content from 37 to 54%, a curing agent for the resin, and a lower secondary alcohol as the solvent, the varnish containing about 50% w/w of the resin. The varnish can be used to form glasscloth laminates for the production of printed circuit boards, copper clad laminates and blading for turbines.

Abstract: Coating compositions capable of liquid application to substrates consist essentially of a curable film forming polyol-containing component and an organic reactive diluent. The reactive diluent is an organic compound containing a primary or secondary hydroxyl group and further characterized by having a retained solids value of greater than about 80 percent, a hydroxyl equivalent weight of from about 180 to about 800, and a liquid viscosity of less than about 10 poise at 60.degree. C. The coating compositions can be formulated to contain little or no volatile organic solvent and/or water.

Abstract: Crosslinked addition polymer microparticles are produced by dispersion polymerization of monomers in an aliphatic hydrocarbon liquid in the presence of a dispersion stabilizer and also of a specified type of amino resin which is insoluble in the hydrocarbon liquid, at least one of the monomers polymerized carrying a group which can react with the amino resin under the conditions of polymerization. Coating compositions having improved application characteristics and/or giving improved film properties are obtained by dispersing the microparticles in combinations of suitable film-forming polymers and diluents.

Abstract: A friction material having an excellent heat-resistance, comprises 5 to 70% by weight of pulp-like particles consisting essentially of a heat-resistant aromatic polymeric material; 1 to 70% by weight of a fibrous material comprising at least one member selected from inorganic fibrous materials and heat-resistant organic fibrous materials; 1 to 35% by weight of a friction-regulating agent and; 5 to 40% by weight of a thermosetting polymeric resin.
