    Abstract: Polymers of the polyphenylene type comforming to the general formulas ##STR1## WHERE X is any number; ##STR2## WHERE N = 1-4 AND R is a simple bond; (CH.sub.2).sub.m with m = 1-20; CH=CH; C.tbd.C; CR.sub.1 R.sub.2 ; ##STR3## WITH P = 1-10, R.sub.1 and R.sub.2 standing for H, lower alkyls or phenyl; O; S; CO; ##STR4## WHERE R.sub.4 is H, Cl, Br, phenyl, ##STR5## with n, R, R.sub.1 and R.sub.2 as defined above. A method for producing said polymers of the polyphenylene type, which comprises polycyclocondensaton of diacetylbenzenes, diacetylnaphthalenes, diacetyl compounds of the general formula ##STR6## with n, R and R.sub.1 as defined above, triacetylbenzenes, 1,3,5-tri(acetylphenyl)benzenes or tri- or tetraacetyloligophenyls, or comprises copolycyclocondensation of the above-said acetyl-substituted aromatic compounds with methylarylketones of the general formula ##STR7## WHERE R.sub.4 is H, Cl, Br, phenyl, ##STR8## with n, R, R.sub.1 and R.sub.2 as defined above, or with monoacetylnaphthalenes in the presence of acid catalysts in a solution, melt or solid phase.The herein-proposed polymers of polyphenylene type feature high thermostability and heat-resistance, are chemically stable and have a number of other valuable properties.
