Abstract

1,222,471. Calcium carbonate filled polymers. DIAMOND SHAMROCK CORP. 24 Jan., 1969, No. 4184/69. Heading C3P. [Also in Division C1] Specially prepared (see Heading C1A) small particle CaCO 3 is added as a filler to ethylenepropylene copolymer elastomers and styrenebutadiene rubber in the ratios of 1: 1 and 1À5: 1 respectively, and are cured at 307‹ C., to give improved tensile and tear properties.
