An improved process for copolymerizing the monomers (a) at least one monomer selected from the group consisting of monoolefins, non-conjugated polyenes, conjugated polyenes, haloolefins, unsaturated esters of carboxylic acids and unsaturated ethers and (b) an acrylic monomer under slurry polymerization conditions to give a copolymer containing the monomeric units (a) and (b) alternately connected to each other with good regularity which has a narrow molecular weight distribution and is not liable to gelling during its formation.
