Doterajší stav technikyBACKGROUND OF THE INVENTION

Deriváty fenolu obsahujúce alkyltiometylovú skupinu v zmesiach so zlúčeninami obsahujúcimi fosfor a/alebo síru sú známe ako stabilizátory pre elastoméry. Napríklad v európskom patente č. 049 133 A je opísaná zmes, ktorá obsahuje 4 zložky. Zmes pozostáva z difenylamínu, trifenylfosfitu, dialkyltiodipropionátu a aspoň jedného alkylfenolu alebo bisfenolu, ako je napríklad bis-(4-hydroxybenzyl)tioéter.Phenol derivatives containing an alkylthiomethyl group in mixtures with phosphorus and / or sulfur containing compounds are known as stabilizers for elastomers. For example, in European patent no. 049 133 A discloses a composition comprising 4 components. The mixture consists of diphenylamine, triphenylphosphite, dialkylthiodipropionate and at least one alkylphenol or bisphenol such as bis- (4-hydroxybenzyl) thioether.

Z US patentu č. 3 658 743 A je známa zmes pre elastoméry, ktorá pozostáva z troch zložiek. Zmes je tvorená fenolom alebo bisfenolom, ako bola predtým uvedená v európskom patente č.049 133 A, organickým sulfidom alebo dialkyltiodialkanolátom a epoxidom alebo fosfitom, ako je napríklad trifenylfosfit.U.S. Pat. No. 3,658,743 A is a known compound for elastomers which consists of three components. The mixture consists of a phenol or bisphenol, as previously disclosed in European Patent No. 049 133 A, an organic sulfide or dialkylthio dialkanolate and an epoxide or phosphite, such as triphenylphosphite.

V DE patentovom spise č. 23 34 163 A je opísaná zmes tvorená 2 zložkami, ktorá pozostáva z fenolu a fosfitu. Stabilizátorová zmes obsahuje napríklad 2,6-dialkyl-substituovaný 4-(alkylmerkaptometyl)fenol, ako fenolickú zložku a 4-alkylalebo 2,4-dialkyl-substituovaný trifenylfosfit.In DE patent no. 23 34 163 A discloses a mixture of 2 components consisting of phenol and phosphite. The stabilizer mixture comprises, for example, 2,6-dialkyl-substituted 4- (alkylmercaptomethyl) phenol as a phenolic component and 4-alkyl or 2,4-dialkyl-substituted triphenyl phosphite.

V US patente č. 3 637 585 A je ďalej uvedená dvojzložková zmes, ktorá obsahuje alkylmerkaptometylfenol, v ktorom alkylový zvyšok nesie 2 alkanoyloxylové substituenty, ako aj dialkyltioalkanoát.U.S. Pat. No. 3,637,585 A is a further two-component composition comprising an alkyl mercaptomethylphenol in which the alkyl moiety carries 2 alkanoyloxy substituents as well as a dialkylthioalkanoate.

V EP patente č. 0 224442 je ako stabilizátor uvedenýIn EP patent no. 0 224442 is disclosed as a stabilizer

6-alkyl-2,4-bis(tiometyl)fenol.6-alkyl-2,4-bis (thiomethyl) phenol.

Samotné fenoly obsahujúce alkyltiometylovú skupinu sú tiež známe ako stabilizátory elastomérov. V európskom patente č. 0 165 209 A sú napríklad opísané 2,4-bis(merkaptometyl)-6-alkylfenoly, ako zvlášť účinné stabilizátory.The alkylthiomethyl-containing phenols themselves are also known as elastomer stabilizers. In European patent no. For example, 2,4-bis (mercaptomethyl) -6-alkylphenols are described as particularly effective stabilizers.

Naďalej však trvá potreba účinných stabilizátorov pre elastoméry> ktoré sú citlivé proti oxidatívnemu odbúravaniu.However, there remains a need for effective stabilizers for elastomers that are sensitive to oxidative degradation.
