Abstract: Metal amine complexes are formed from amines adhering to the general formulas ##STR1## by reaction with various metal salts. Prior to reaction with various metal salts, the above amines may first be reacted with a formaldehyde source or with a formaldehyde source followed by an epoxide or with an epoxide or with an epoxide followed by a formaldehyde source. The resultant metal amine complexes are then employed in asphalt compositions in order to increase the overall strength of such compositions.

Abstract: The physical properties of bitumen/aggregate compositions are improved bya. adding an antistripping agent selected from imidazolines, polyamines, alkoxylated polyamines, aminocarboxylic esters, amide-amines and mixtures thereof to a bituminous material;b. adding Portland cement to an aggregate; andc. blending the products of steps a. and b.

Abstract: Compositions for stabilizing halogen-containing organic polymers against the deteriorative effects of heat, light and weathering and which are non-irritating to eyes and mucous membranes, comprise the reaction product produced by combining an organotin oxide, an ethylenically unsaturated dicarboxylic acid ester and a mercaptan, wherein the chemical equivalence of the mercaptan is less than the chemical equivalence of the diorganotin oxide and the chemical equivalence of the diorganotin oxide is less than the chemical equivalence of the ester compound.

Abstract: This invention relates to stabilizer compositions for polymers comprising (1) an organotin compound, or mixture of organotin compounds, (2) a mercaptan-containing organic compound or mixture of mercaptan-containing organic compounds, and, optionally, (3) a halogen-containing tin compound or mixture of halogen-containing tin compounds, said stabilizers having a total halogen content of about 0.1% to about 10% by weight based on the weight of the stabilizer composition. This invention also relates to polymer compositions containing said stabilizers, to a process for stabilizing polymer by adding thereto said stabilizers, and to articles of manufacture, e.g. pipe, comprising a polymer and said stabilizers.
