Phenol, water and an alkaline catalyst, limited to 0.5-2.2 moles of catalyst per 100 moles of phenol and preferably lithium carbonate, are mixed with formaldehyde at 1.9-5.0 formaldehyde to phenol ratios. The reaction mixture is heated at a uniform rate over 1 hour to reflux temperature and refluxed until a viscosity of 400-500 centipoise at 50-75% solids is attained. The mixture is cooled to 50.degree. C. and neutralized with acid to a pH of 3-7, preferably with citric acid. The resulting resin may be employed, without solvent dilution, to make resin-fiberglass laminates that have strengths comparable to polyester or epoxy laminates. The laminates have exceptional fire resistance and low smoke evolution when exposed to flame.

    • A ruminant repellent composition effective to discourage browsing of edible material, especially living vegetable matter, is the decomposition product of a lipoidal material admixed with a lipolytic enzyme. One such composition is produced by admixing fish, such as whole salmon, with a source of lipolytic enzyme, such as visceral enzyme from feeding fish, or pancreatic enzyme derived from hog or beef pancreas. The effectiveness of the mixture can be increased by admixing additional lipoidal material such as fish oil, for example, tuna oil with the fish prior to decomposition. The active portion of the decomposition product of the lipoidal material and the lipolytic enzyme can be extracted with a water immiscible, organic solvent, such as dichloromethane, to separate the water soluble phytotoxins present in the decomposition product and to concentrate the active ruminant repellent components from the decomposition product.

    • A ruminant repellent is a composition which, when applied directly to or applied to the area surrounding edible material such as living plants, discourages ruminant animals from browsing such edible material. The ruminant repellent of the invention comprises a composition of matter containing a phospholipid as an active repellent ingredient. Phospholipids extracted from animal or plant lipoidal material contain the active repellent material which effectively discourages browsing by ruminants. Within the phospholipid fraction, lecithin and cephalin are active repellent components. Examples of phospholipid source materials which can be applied to edible material to effectively repel ruminants are unputrefied whole eggs, dried, powdered whole eggs, unputrefied egg yolk, and lipoidal material derived from ground shellfish and fish (such as shrimp or anchovy). If desired, preservatives can be added to the repellent composition to prevent or delay putrefaction in order to form a long lasting product. Some examples of preservatives which can be used are formaldehyde, benzoic acid, sodium proprionate, and inorganic salts such as sodium chloride. Alternatively, a phospholipid solvent such as isopropanol can be combined with the phospholipid source material to function both as a phospholipid extracting solvent and as a preservative. The repellent composition can be applied to edible material in pure form (with or without a preservative), but is preferably applied to or around the edible material as a minor proportion of a mixture comprising the repellent composition, a solvent for the phospholipids in the lipoidal source material, and a carrier (or diluent). Both aqueous and nonaqueous carriers can be effectively utilized.
