  Additives suitable for improving the flow and/or depressing the cloud point of crude oils, lubricating oils and especially fuel oils are polymers containing defined alkyl groups of at least 8 carbon atoms chain length. Such polymers are either (a) of a mixture of monomers having only two alkyl groups one being at least 3 carbon atoms longer than the other or (b) of a mixture of monomers having only three alkyl groups each differing by at least 3 carbon atoms and the middle alkyl group being half the combined length of the other two. Alternatively, the polymer may be derived from a monomer having the two defined alkyl groups (a) or the three defined alkyl groups (b).

  适用于改善原油、润滑油，特别是燃料油的流动性和/或降低浊点的添加剂是含有至少 8 个碳原子链长的确定烷基的聚合物。这种聚合物可以是 (a) 单体的混合物，其中只有两个烷基，其中一个比另一个至少长 3 个碳原子；或者 (b) 单体的混合物，其中只有三个烷基，每个烷基至少相差 3 个碳原子，中间的烷基是另外两个烷基总长度的一半。或者，聚合物可以由具有两个定义的烷基（a）或三个定义的烷基（b）的单体衍生而来。

  Provided is a novel layer migration control agent that is added to a paint composition when forming a multilayer coating film on a coating object by curing a prime coating film and a top coating film at the same time, the agent making it possible to control layer migration of the two coating films and obtain the multilayer coating film with satisfactory finish appearance. The layer migration control agent is a copolymer obtained by copolymerization of a monomer mixture including 5% by weight to 90% by weight of a polymerizable unsaturated monomer including an ether group and 10% by weight to 95% by weight of a polymerizable unsaturated monomer having a hydrophobic group having 1 to 22 carbon atoms, the copolymer having a weight average molecular weight of 1000 to 100,000.
