ABSTRACT:
Polymers of 1,000 to 50,000 number average molecular weight, comprising 3 to 40 molar proportions of ethylene per molar proportion of an ethylenically unsaturated monomer, are prepared using an ester peroxide as the free radical initiator, in a solvent, for use as wax crystal modifying agents, e.g., pour depressants and flow improvers for middle distillate fuel oil.
