COPOLYMERS OF MALEIC ANHYDRIDE AND AN ALIPHATIC ALPHAOLEFIN HAVING FROM SIX TO TEN CARBON ATOMS ARE PREPARED IN A FINELY DIVIDED FILTERABLE SOLID FORM. MALEIC ANHYDRIDE IS COPOLYMERIZED WITH AT LEAST ONE OF THE OLEFINS IN THE PRESENCE OF A FREE-RADICAL CATALYST AND A SOLVENT FOR BOTH OF THE MONOMERS AND THE RESULTING COPOLYMER. THE COPOLYMER IS PRECIPITATED BY ADDING THE REACTION SOLUTION TO A SUFFICIENT AMOUNT OF A MONOHYDROXY ALIPHATIC ALCOHOL HAVING FROM ONE TO FOUR CARBON ATOMS. |
