An object of the present invention is to provide a multi-component polar olefin copolymer which has sufficiently improved solvent solubility without impairing mechanical properties and the like. The present invention relates to a multi-component polar olefin copolymer containing: one kind of unit of nonpolar monomer (X1) that is ethylene or an α-olefin having 3 to 10 carbon atoms; one or two or more kinds of units of polar monomers (formula (1), Z1); and structural unit(s) of one or two or more kinds of units of nonpolar monomers (X2) that are different from the above X1 and/or one or two or more kinds of units of polar monomers (formula (2), Z2):
H2C=CH-COO⁅Q⁆T1 ... (1)
H2C=CH-T2 ... (2)
本发明的目的是提供一种多组分极性烯烃共聚物,该共聚物具有足够好的溶剂溶解性,同时不影响机械性能等。本发明涉及一种多组分极性烯烃共聚物,它含有一种非极性单体单元(X1),它是
乙烯或具有 3 至 10 个碳原子的 α-烯烃;一种或两种或多种极性单体单元(式 (1),Z1);以及一种或两种或多种非极性单体单元的结构单元(X2),它不同于上述 X1 和/或一种或两种或多种极性单体单元(式 (2),Z2):
H2C=CH-COO⁅Q⁆T1 ...... (1)
h2c=ch-t2 ... (2)
