Decoratable polyolefin plastics

Abstract

Abstract A POLYOLEFIN COMPOSITION COMPRISING (1) ABOUT 35 TO 92 PERCENT OF A CRYSTALLINE POLYMERR OF AN A-OLEFIN HAVING 2 TO 8 CARBON ATOMS CONTAINING AT LEAST 90 PERCENT A-OLEFIN UNITS AND AT LEAST PART OF WHICH HAS BEEN CHEMICALLY COMBINED WITH MALEIC ANHYDRIDE, (2) 0 TO 30 PERCENT OF A CRYSTALLINE ETHYLENE POLYMER HAVING A DENSITY OF ABOUT 0.91 TO ABOUT 0.97, (3) ABOUT 5 TO 20 PERCENT OF AN ETHYLENEPROPYLENE COPOLYMER RUBBER CONTAINING 20 TO 80 PERCENT ETHYLENE UNITS, AND (4) ABOUT 0.5 TO ABOUT 15 PERCENT OF AN ABIETIC ACID ESTER OF THE FORMULA 1-(R-OOC-),1,4A-DI(CH3-),7-(CH3-CH(-CH3)-)-1,2,3,4,4A,5,6, 10-OCTAHYDROPHENANTHRENE WHEREIN R IS A HYDROCARBYL GROUP CONTAINING 1-8 CARBON ATOMS. THESE POLYOLEFIN PLASTICS EXHIBIT EXCELLENT ADHESION TO PAINTS, LACQUERS, AND INKS WITHOUT THE NEED FOR EXPENSIVE PRIMERS OR OTHER SURFACE TREATMENT. THEY ALSO EXHIBIT ADVANTAGEOUS IMPACT STRENGTH, ESPECIALLY AT LOW TEMPERATURES.
