1,050,548. Oxidized polypropylene. EASTMAN KODAK CO. March 6, 1964 [March 19, 1963], No. 9500/64. Heading C3P. An emulsifiable composition comprises the product of oxidation of a blend of amorphous polypropylene having a viscosity measured at 150‹ C. of 1000 to 200,000 c.p.s. and a wax material having a viscosity measured at 125‹ C. of 100 to 20,000 c.p.s., the wax material being polyethylene, hydrogenated polyethylene, ethylene-isopropanol telomer or ethylene-isobutanol telomer or a mixture thereof. The polyethylene may be a degraded higher molecular weight polyethylene. 'The weight ratio of polypropylene to polyethylene is preferably 1: 1. |
