Abstract: A torchable roll roofing membrane which comprises a reinforcing mat which is saturated and coated with bituminous composition comprising a bituminous component and, optionally, an unhydrogenated block copolymer of a monoalkenyl aromatic hydrocarbon and a conjugated diolefin, and coated onto one surface, a bituminous composition comprising a bituminous component and a hydrogenated block copolymer of a monalkenyl aromatic hydrocarbon and a conjugated diolefin.

Abstract: A weatherproof coating for roofs or decks is formed when an adhering material is used in conjunction with a nonwoven mat formed from a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon.

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: Formaldehyde adducts of amines, polyamines and amides conforming to the general formula ##STR1## are employed in asphalt compositions in order to improve the overall adhesion between the asphalt and aggregate or glass fiber or glass fiber mesh and to thereby increase the tensile strength of the asphalt composition.

Abstract: In accordance with this invention there are provided compositions of matter comprising a bitumen containing material and an epoxylated polyamine wherein at least two of the amino nitrogen atoms are separated by six carbon atoms. These compositions provide improved adhesion between aggregate materials and the bitumen containing material.

Abstract: In accordance with this invention there are provided organic antimony stabilizer compositions effective in stabilizing halogen containing organic polymers against the deteriorative effects of heat comprising (1) at least one organic antimony compound having at least one antimony to sulfur to carbon (i.e. Sb-S-C) linkage, (2) elemental sulfur, and (3) at least one 2-mercaptocarboxylic acid. Said 2-mercaptocarboxylic acid and elemental sulfur also serve to provide hydrolytic and UV light stability to the antimony compound per se. Also provided are stabilized organic polymer compositions comprising a halogen containing polymer and said organic antimony stabilizer composition.

Abstract: A bitumen composition comprising an asymmetric, radial polymer containing a plurality of block copolymer arms comprising at least one polymeric block of a monoalkenyl aromatic hydrocarbon and at least one polymeric block of a conjugated diolefin polymer and a plurality of conjugated diolefin polymer arms. The bitumen composition exhibits increased toughness and tenacity as determined by the Benson method and is particularly useful in road paving applications. Best results are achieved when the asymmetric, radial block copolymer is sulfur vulcanized after incorporation into the bitumen composition.

Abstract: A bituminous composition comprising: (a) a bitumen, (b) a block copolymer of at least one conjugated diolefin and at least one vinyl aromatic hydrocarbon, and (c) a thermoplastic or low crystallinity polymer.
