Abstract

A composition particularly for golf-ball covering material contains gutta-percha or balata, and a product formed by co-polymerizing an aromatic vinyl compound and a conjugated-diene hydrocarbon in a natural rubber latex. Preferably styrene and butadiene are used in molar proportions of 60:40 to 76:24, or in proportions of 70:30 to 90:10 by weight, in natural rubber latex, the combined weight of styrene and butadiene being in the proportion of 5:6 to 5:1 in relation to the weight of natural rubber in the latex. The composite latex is coagulated, and the coagulum mixed with gutta percha or balata, and vulcanizing and other ingredients which may include natural rubber. Alternatively natural rubber latex may be added to the composite latex and the mixed latices coagulated. In one of the examples butadiene and styrene are copolymerized in natural rubber latex as described in Specification 652,401, to provide a composite copolymer comprising 50 parts natural rubber and 50 parts of a copolymer of butadiene and styrene (in the proportions of 20 : 80 by weight). The composite latex is then mixed with natural rubber latex, 17 parts by weight of natural rubber being added to 72 parts of the composite copolymer. The dispersion is coagulated with dilute acetic acid, and the coagulum mixed with 76.7 parts of gutta percha, and vulcanizing ingredients and fillers.ALSO:A rubber composition particularly for use as golf-ball covering material contains gutta-percha, or balata, and a substance formed by co-polymerizing an aromatic vinyl compound and a conjugated-diene hydrocarbon in a natural rubber latex.
