ABSTRACT:
There is provided a lactam ring-containing polymer comprising: 20 to 100 molar % of a structural unit represented by the general formula (1); 0 to 70 molar % of a structural unit represented by the general formula (2); and 0 to 70 molar % of a structural unit represented by the general formula (3) and/or a structural unit represented by the general formula (4): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 each represents a hydrogen atom or a methyl group, and X represents COOR.sup.4 and/or CONR.sup.5 R.sup.6 in which R.sup.4, R.sup.5 and R.sup.6 each represents a hydrogen atom or a C1-C4 alkyl.
The polymer is excellent in heat resistance and is expected to be used for resin modifiers, polymeric additives for petroleum tertiary recovery, and other various applications.
