description ABSTRACT The synthesis of poly-5,7-diallyl-25,26,27,28-tetrahydroxycalix[4]arenewere performed in experimental series as follows: (1) Cyclotetramerizationof p-t-butylphenol with NaOH and paraformaldehyde to p-butylcalix[4]arene, (2) Debutylation of p-butylcalix[4]arene using AICI3and phenol to tetrahydroxycalix[4]arene,(3) Allylation reaction using allylbromide to diallyloxy-dihydroxycalix[4]arene,(4) Claisen rearrangement reaction, (5) Cationic polymerization to diallylcalix[4]arenesA.ll of the synthesizedproductswere analyzedby meansof IR spectrometerand 1H-NMR spectrometer. The result of 25,27-diallyloxy-26,28-dihydroxycalix[4]arenesynthesis was white crystals having m.p. 205-207 °C in 80.95% yield. The synthesis of 5,7-diallyl-25,26,27,28-tetrahydroxy-calix[4]arenegave light yellow crystals having m.p. 214-216 °C in 78.67% yield. The polymerization gave poly(5,7-diallyl-25,26,27,28-tetrahydroxycalix[ 4]arene)having m.p. 338-340 °C, in 60% yield. Its estimated has a relative molecular weight of 18,738 glmol with the number of unit repetition about 37 monomer units. Keywords: Diallylation, polymerization, Poly-5, 7-diallyl-25, 26, 27,28-tetrahydroxycalix[4]arene
