Abstract: A four-component composition is disclosed comprising a hydroxyl-bearing polymer; a liquid, amino- or hydroxyaromatic diluent having an atmospheric boiling point of about 150.degree. C. or greater; an aminoplast or phenolic resin capable of curing the hydroxyl-bearing polymer and a strong acid catalyst for the reaction between the first and third components. Optionally, a pigment may be added to the composition.

Abstract: A process is provided for producing a pressure-sensitive carbonless record sheet comprising the steps of preparing a hot melt coating composition, the hot melt coating composition being water insoluble and having a melting point of from about 60.degree. C. to about 140.degree. C. The hot melt coating composition includes a chromogenic material. The chromogenic material is a meltable color developer of the acidic electron accepting type. The hot melt coating composition is heated to a temperature above its melting point and the heated coating composition is applied to a substrate, the coating composition being applied at a coat weight of from about 0.2 pounds to about 8.0 pounds per 3300 square feet of substrate. The coating composition is set by cooling the coated substrate. A novel liquid chromogenic coating composition is produced, the coating composition having a melting point of from about 60.degree. C. to about 140.degree. C.

Abstract: A thermosetting binder composition for coating, comprising:(I)(1) A non-acidic resinous saturated compound having a molecular weight of at least 900, and an alcoholic hydroxyl content of at least 0.2 eq./100 g;(2) A non-acidic polyester of a polycarboxylic acid crosslinking agent having more than one .beta.-hydroxyl ester group per molecule, and at least one of components (1) and (2) having an alcoholic hydroxyl functionality of more than 2, and(II) A transesterification-promoting metal salt or complex curing catalyst which is soluble in liquid hydrocarbons.For aqueous compositions, component (I) (1) is preferably a neutralized epoxy resin/amine adduct and component (II) should be insoluble in water; they can be used for cathodic electrodeposition.

Abstract: Polyolefin resins are rendered stable against degradation caused by exposure to heat and oxygen in the presence of copper by the incorporation of a novel polymeric stabilizer functioning dually as an antioxidant and a chelating agent.

Abstract: A curable composition comprising (1) at least one rubber selected from the group consisting of natural rubber, a diene rubber and a diene copolymer rubber, (2) a sulfide resin as a curing agent having the following general formula: ##STR1## wherein X is methylene group, ethylene group, --S-- or --S--S--, R.sup.1 and R.sup.2 are independently a C.sub.1-10 alkyl or alkylene group, Y.sup.1 and Y.sup.2 are independently the residue of a phenol compound, p is an integer of 2 to 8, and n is an integer of 2 to 5, (3) a phenolic thermosetting resin and (4) a hardener for hardening said thermosetting resin. The composition shows a low viscosity upon milling and also does not take place scorching and blooming, and can provide a cured rubber having a high dynamic modulus of elasticity with improved workability and processability. The cured rubber is suitable for use in radial tires as bead filler rubber.

Abstract: Improved limed resinates are disclosed. The calcium resinates comprise the reaction product of calcium hydroxide with:(a) a rosin modified phenol formaldehyde condensate and(b) an .alpha.-olefin-maleic anhydride partial ester or polyanhydride.Printing inks containing the improved limed resinates are also disclosed.

Abstract: Phenolic aldehyde resins used in adhesive coatings for binding substrates to rubber are modified to provide better adhesion and to decrease the problem of blowholes on the substrate coated with the adhesive coating. The resin is modified by incorporating into the resin a compound selected from the group consisting of urea, thiourea, thionamide having one to six carbon atoms or mixture thereof. In the method of preparing the modified phenolic aldehyde resin about 1 to about 10 weight percent based on the resin is added to the aqueous solution either simultaneously with or sequentially after the addition of the phenolic compound and aldehyde. The modified phenolic resin is then combined with an elastomeric latex or latices to produce the improved adhesive coating.

Abstract: A blend of rubber comprising 100 parts of a rubber, from 5 to 150 parts of a carbazole/phenol/formaldehyde resin, from 1 to 5 parts of a vulcanizing agent for the rubber and from 5 to 15 parts per hundred parts of the resin of a formaldehyde donor, is made up. This is done in any usual manner. The blend is then heated, preferably under pressure, to vulcanize the rubber and cross-link the resin. A preferred method of making the resin is described. The invention also comprises reinforced rubbers made according to the process.
