Zusammenfassung:	1,134,018. Propylene-butene copolymer compositions. EASTMAN KODAK CO. 21 Jan., 1966 [22 Jan., 1965], No. 33268/68. Divided out of 1,134,017. Heading C3P. Normally solid white thermoplastic compositions comprise (A) a normally solid propylene/butene-1 copolymer, (B) finely divided zinc oxide at a concentration sufficient to pigment the copolymer and (C) 0À1 to 1 weight per cent based on the copolymer of a zinc N,N- di - (C 1-20 alkyl) dithiocarbamate or dilauryl 3,31-thiodipropionate. Conventional additives may also be incorporated, and the compositions may be formed by roll compounding, extrusion or solvent mixing. The compositions may be moulded into films, sheets, bars, tubes or filaments. Examples describe compositions of propylene/butene copolymers, zinc oxide and zinc N,N-dibutyldithiocarbamate or dilauryl thiodipropionate.
