Claims
- 1. A polymer, which is obtained by heating an imide of formula I ##STR14## in which E is allyl or methallyl, n is 1 or 2 and, when n is 1, R is hydrogen, alkyl having 1-12 C atoms, alkenyl having 3-6 atoms, cycloalkyl having 5-8 C atoms, phenyl, tolyl, xylyl or naphthyl, or benzyl or, when n is 2, R is --C.sub.m H.sub.2m --, in which m is an integer of 2-20, m-phenylene, p-phenylene, 1,3-naphthylene, 1,4-naphthylene or 1,5-naphthylene or a group of the formula II ##STR15## in which T is methylene, isopropylidene, CO, O, S or SO.sub.2, at a temperature between 180.degree. and 300.degree. C. for 6 to 24 hours.
- 2. A polymer according to claim 1 where in the imide of formula I E is allyl.
- 3. A polymer according to claim 1 where in the imide of formula I
- E is the allyl group and, when n is 1, R is hydrogen, alkyl having 1-8 C atoms, allyl, cyclohexyl, phenyl or benzyl, or, when n is 2, R is --(CH.sub.2).sub.m --, in which m is an integer of 2-12, m- or p-phenylene or a group of the formula II ##STR16## in which T is the methylene group, O or SO.sub.2.
- 4. A polymer according to claim 1 where in the imide of formula I
- E is the allyl group, n is the number 2 and R is --(CH.sub.2).sub.2 --, --(CH.sub.2).sub.6 -- or ##STR17##
- 5. A polymer according to claim 1 where the imide of formula I is ##STR18##
- 6. A polymer according to claim 1 where the imide of formula I is ##STR19##
- 7. A polymer according to claim 1 where the imide of formula I is ##STR20##
- 8. A polymer according to claim 1 which is obtained by heating an imide of formula I where E is allyl, n is 2 and R is ##STR21## at a temperature of 240.degree. to 250.degree. C. for 6 to 12 hours.
