Polymers containing adamantane moieties are a kind of high performance materials.This work concentrates primarily on the synthesis and properties of polyarylates based adamantane.New adamantylhydroxybenzene monomers

4-(1-adamantyl)-1

3-benzenediol(ADRL) and 1

3-bis(4-hydroxyphenyl) adamantane (BHAD) were synthesized from adamantane and characterized by means of IR

H NMR

3C NMR and elemental analysis.Novel polyarylates (P1

P2) were synthesized from terephthalyl chloride and ADRL

BHAD as diphenols by aqueous/organic two-phase interfacial polycondensation

using benzyltriethylammonium chloride as phase transfer catalyzer.The synthesized polyarylates containing adamantane moieties were amorphous

and dissolved in a variety of solvents such as DMSO

NMP

DMF and DEC.The thermal properties were measured by DSC and TG.The results showed that glass transition temperatures were respectively 214℃(P1) and 189℃(P2).The 10% mass loss temperatures of polyarylates were above 400℃.Investigation of reaction conditions revealed that BHAD was easier to dissolve in sodium [JP+4]hydroxide solution and obtain high molecular weight polyarylates than ADRL under the same conditions.Inherent viscosities were measured in NMP at 30℃.The maximum inherent viscosities of P1 and P2 were 43 ml·g-1 and 76 ml·g-1

respectively.
