Abstract

A polymer obtained by polymerizing, in a presence of a polymerization initiator, a compound having a cage structure with at least 11 carbon atoms and an ethylenic double bond; a film forming composition containing the polymer; an insulating film formed using the composition; and an electronic device.

Claims (24)

1. A polymer obtained by polymerizing, in the presence of a polymerization initiator, a compound having a cage structure with at least 11 carbon atoms and an ethylenic double bond,

wherein the compound having a cage structure is represented by formula (I):

wherein when two or more R's are present, the R's each independently represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an acyl group or a silyl group;

m represents an integer of from 1 to 14;

X represents any substituent; and

n represents an integer of from 0 to 13.

2. The polymer according to claim 1 ,

wherein the polymerization initiator is selected from the group consisting of organic peroxides and azo compounds.

3. The polymer according to claim 1 , which has a solubility, in cyclohexanone at 25° C., of 3 mass % or greater.

4. A film forming composition comprising a polymer according to claim 1 .

5. A film forming composition comprising:

a compound having a cage structure with at least 11 carbon atoms and an ethylenic double bond; and

a polymerization initiator,

wherein the compound having a cage structure is represented by formula (I):

wherein when two or more R's are present, the R's each independently represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an acyl group or a silyl group;

m represents an integer of from 1 to 14;

X represents any substituent; and

n represents an integer of from 0 to 13.

6. The film forming composition according to claim 4 , which further comprises a coating solvent.

7. An insulating film formed by utilizing a film forming composition according to claim 4 .

8. An electronic device comprising an insulating film according to claim 7 .

9. The film forming composition according to claim 5 , which further comprises a coating solvent.

10. An insulating film formed by utilizing a film forming composition according to claim 5 .

11. An electronic device comprising an insulating film according to claim 10 .
