Abstract: 1,185,226. Hot melt adhesive compositions. SUN OIL CO. 15 March, 1967 [18 March, 1966], No. 12145/67. Addition to 1,116,551. Headings C3P and C3R. A thermoplastic hot melt adhesive composition comprises a homogeneous mixture of 35 to 75 weight per cent of an aromatic hydrocarbonaldehyde resin free from acetate groups and having a ring and ball softening point of 70‹ to 150‹ C. and 25 to 65 weight per cent of an ethylene-vinyl acetate copolymer containing 17 to 42 weight per cent vinyl acetate. In an example there is described a resin obtained by reacting formaldehyde with a gas oil fraction containing aromatics, which is suitable for blending with copolymers of ethylene and vinyl acetate.

Abstract: Hot melt adhesives comprise a major proportion by weight of atactic polypropylene having a Brookfield viscosity of 4200 to 5800 cp at 300 DEG F. and a ring and ball melting point of 115 DEG to 121 DEG C., and a minor proportion by weight of at least one material selected from tall oil, terpene resins, polyethylene, isotactic polypropylene and hydrocarbon/aldehyde resins. Specified terpene resins are polymers of a - and b -pinene. The hydrocarbon/aldehyde resins may be derived from refinery feedstocks containing 15 to 15% aromatic hydrocarbons and formaldehyde, formalin, paraldehyde, trioxane, acetaldehyde, propionaldehyde or butyraldehyde, in the presence of catalysts such as sulphuric, hydrofluoric, formic and phosphoric acids, boron trifluorides and metal chlorides, particularly sulphuric acid or boron trifluoride in the presence of acetic acid. The adhesives may be used for laminating paper, aluminium foils and polypropylene and regenerated cellulose films. Examples describe the preparation of aldehyde resins by heating catalytic gas oil with paraformaldehyde in the presence of (III) boron trifluoride/acetic acid and (IV) sulphuric acid/acetic acid catalysts, and hot melt adhesive compositions comprising atactic polypropylene, phenolic antioxidant and (I) tall oil, (III-V) hydrocarbon/aldehyde resin and/or isotactic polypropylene, (VI and VII) a -pinene polymers and/or isotactic polypropylene, (VIII) isotactic polypropylene and (IX) polyethylene.
