The synthesis of poly-5,7-diallyl-25,26,27,28-tetrahydroxycalixarene were performed in experimental series as follows: (1) Cyclotetramerization of p-t-butylphenol with NaOH and paraformaldehyde to p-butylcalixarene, (2) Debutylation of p-butylcalixarene using AlCl3 and phenol to tetrahydroxycalixarene, (3) Allylation reaction using allylbromide to diallyloxy-dihydroxycalixarene, (4) Claisen rearrangement reaction, (5) Cationic polymerization to diallylcalixarenes.
