Reaction Steps
An ethylene/maleic anhydride trunk copolymer was prepared which contained 86.5 weight percent ethylene and 13.5 weight percent maleic anhydride. The copolymer was pumped by an extruder through a tube heated to about 500° C. to reduce the molecular weight. The melt viscosity was 600 centipoises at 140° C. The average chain length was about 300 carbon atoms.
