- 6. A method as claimed in claim 4 wherein the resulting polymers are transformed into infusible and insoluble products by condensing the terminal groups of these polymers at a temperature within a range from 200.degree. to 300.degree. C.
- 7. A method as claimed in claim 4, wherein the resulting polymers are reacted under the same conditions with a monoarylketone represented by the formula ##STR22## with R.sub.1 being H, lower alkyl or phenyl and R.sub.2 being H or phenyl.
- 8. A method as claimed in claim 1 wherein the resulting polymers are transformed into infusible and insoluble products by condensing the terminal groups of said polymers at a temperature within a range from 150.degree. to 300.degree. C.
- 9. A method for producing phenylene-type polymers comprising copolycyclocondensing compounds selected from the group consisting of diacetylbenzenes; diacetyl-naphthalenes; diacetyl compounds represented by the formula ##STR23## where R is a simple bond, (CH.sub.2).sub.m with m=1-20, O, or S; triacetylbenzenes, or 1,3,5-tri (acetylphenyl)benzenes, with compounds selected from the group of methylarylketones represented by the formula ##STR24## wherein R.sub.1 is H, lower alkyl or phenyl; R.sub.2 is H or phenyl; in the presence of inorganic acid catalysts at a temperature within a range from -40.degree. to 300.degree. C.
- 10. A method as claimed in claim 9 wherein said copolycondensation is carried out in a solvent of polyphosphoric acid at a temperature within a range from 100.degree. to 120.degree. C.
- 11. A method as claimed in claim 10 wherein the resulting polymers are transformed into infusible and insoluble products by condensing the terminal groups of these polymers in the presence of inorganic acid catalysts at a temperature within a range from 150.degree. to 300.degree. C.
- 12. A method as claimed in claim 9 wherein said method is carried out in an organic solvent selected from the group consisting of aromatic hydrocarbons, chlorinated hydrocarbons, alcohols, glycols, ethers and phenols.
- 13. The method of claim 9 wherein the method is carried out in a solvent selected from the group consisting of aromatic hydrocarbons and chlorinated hydrocarbons.
- 14. A method as claimed in claim 12, wherein said method is carried out in the presence of a ketalyzing agent selected from the group consisting of triethyl orthoformate, dimethylsulfite, and triethyl orthosilicate.
- 15. A method as claimed in claim 14, wherein the resulting polymers are transformed into infusible and insoluble products by condensing the terminal groups of these polymers in the presence of inorganic acid catalysts at a temperature within a range from 150.degree. to 300.degree. C.
- 16. A method as claimed in claim 14 wherein the resulting polymers are transformed into infusible and insoluble products by condensing the terminal groups of these polymers at a temperature within a range from 200.degree. to 300.degree. C.
- 17. A method as claimed in claim 14 wherein the resulting polymers are reacted under the same conditions by a monoarylketone represented by the formula ##STR25## with R.sub.1 being H, Cl, Br, phenyl or ##STR26## and R.sub.2 being H or phenyl.
- 18. A method as claimed in claim 9 wherein the resulting polymers are transformed into infusible and insoluble products by condensing the terminal groups of these polymers at a temperature with a range from 150.degree. to 300.degree. C.
