N-SUBSTITUTED IMIDES AS POLYMERIZATION INITIATORS

摘要

The invention relates to novel N-substituted imides and polymerizable compositions com¬ prising these N-substituted imides. The invention further relates to the use of N-substituted imides as polymerization initiators. The imides are compounds of the formula (I) and (II) wherein n is 1 or 2; m is 1 or 2; R<SUB>1</SUB> and R<SUB>2</SUB> are each, independently of one another, hydrogen, C<SUB>1</SUB>-C<SUB>18</SUB>alkyl, C<SUB>1</SUB>-C-<SUB>18</SUB>alkenyl C<SUB>6</SUB>-C<SUB>14</SUB>aryl, aralkyl, C<SUB>5</SUB>-C<SUB>12</SUB>cycloalkyl, each of which may be substituted by halogen, C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, hydroxy, C<SUB>1</SUB>-C<SUB>6</SUB>alkoxy, carbonyl, C<SUB>1</SUB>-C<SUB>6</SUB>alkoxycarbonyl; or R<SUB>1</SUB> and R<SUB>2</SUB> together with the adjacent -CO-N-CO- group may form a monocyclic, bicyclic or polycyclic ring, said ring having up to 50 non hydrogen atoms and wherein said ring may contain the structural element (formula III) more than once; R<SUB>3</SUB> if n is 1, is C<SUB>1</SUB>-C<SUB>18</SUB>alkyl, C<SUB>6</SUB>-C<SUB>14</SUB>aryl, aralkyl, C<SUB>5</SUB>-C<SUB>12</SUB>cycloalkyl, OR<SUB>10 </SUB>or SR<SUB>11</SUB>, NR<SUB>12</SUB>R<SUB>13</SUB>; wherein R<SUB>3</SUB> if n is 2, is C<SUB>2</SUB>-C<SUB>12</SUB>alkylene, C<SUB>6</SUB>-C<SUB>14</SUB>arylene, xylylene R<SUB>4</SUB> and R<SUB>5</SUB>, correspond to R<SUB>1</SUB> and R<SUB>2</SUB>; R<SUB>6</SUB> if n is 1, is hydrogen, C<SUB>1</SUB>-C<SUB>18</SUB>alkyl, C<SUB>6</SUB>-C<SUB>14</SUB>aryl, aralkyl, C<SUB>5</SUB>-C<SUB>12</SUB>cycloalkyl, NR<SUB>14</SUB>R<SUB>15</SUB>; wherein R<SUB>6</SUB> if n is 2, is C<SUB>2</SUB>-C<SUB>12</SUB>alkylene, C<SUB>6</SUB>-C<SUB>14</SUB>arylene, xylylene; R<SUB>7</SUB> is hydrogen, C<SUB>1</SUB>-C<SUB>18</SUB>alkyl, C<SUB>6</SUB>-C<SUB>14</SUB>aryl, aralkyl, C<SUB>5</SUB>-C<SUB>12</SUB>cycloalkyl, each of which may be substituted by halogen, C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, hydroxy, C<SUB>1</SUB>-C<SUB>6</SUB>alkoxy, carbonyl, C<SUB>1</SUB>-C<SUB>6</SUB>alkoxy- carbonyl; or R<SUB>7</SUB> and R<SUB>14</SUB> or R<SUB>7 </SUB>and R<SUB>15</SUB> form together with the N-atom attached to R<SUB>7 </SUB>a 5- 6 membered ring, optionally interrupted by -NH-, -N(C<SUB>1</SUB>-C<SUB>8</SUB>alkyl)-, -O- and/or S-atoms.
