发明名称 PROCESS FOR PRODUCING HOMOGENEOUS MODIFIED COPOLYMERS OF ETHYLENE/ALPHA-OLEFIN CARBOXYLIC ACIDS OR ESTERS
摘要 A homogeneous, random interpolymer of ethylene and an alpha-olefinically unsaturated carboxylic acid or ester having melt indices from 0.1 to 300 grams/10 minutes, as determined by ASTM D-1238 (190 .degree.C/2160 grams), is improved during its manufacture when made in a substantially constant environment in a stirred autoclave under substantially steady-state conditions of temperature, pressure, and flow rates, said temperature and pressure bein g sufficient to produce a single phase reaction, using a free-radical initiator, said improvement being obtained by the use of a minor amount of a telogenic modifier in the reaction mixture, the process being further characterized by the use of either, or both, of (a) a temperature which is lower than that which would be required without the presence of the telogen, or (b) a pressure whi ch is higher than that which would be required without the presence of the modifier.
