DESCRIZIONE DESCRIPTION
La presente invenzione riguarda composizioni di ritardo della fiamma. The present invention relates to flame retardant compositions.
E* noto che si possono usare composti organici contenenti bromo come agenti di ritardo della fiamma in sistemi di polimeri. Questi agenti di ritardo ;della fiamma noti, contenenti bromo, sono, tradizionalmente, idrocarburi aromatici oppure cicloalifaticij fenoli, eteri oppure poliolibromurati.Questi composti noti vengono impiegati, in generale, ma non invariabilmente, insieme con un co-additivo, in particolare con ossido di antimonio, per potere impiegare quantità minori del composto contenente bromo, conservando un sufficiente livello di attività di ritardo della fiamma. ;Una classe ampiamente usata di agenti di ritardo della fiamma sono composti arilossilici bromurati nell'anello. Tuttavia, questi agenti di ritardo della fiamma noti hanno 1'incoveniente costi ;tuito dal fatto che,in seguito a pirolisi, possono produrre benzodiossine e/o benzofurani bromurati ;tossici. Inoltre, in alcuni casi, la stabilità termica e/o la stabilità-UV di tali agenti di ritardo ;della fiamma noti può non essere sufficiente. ;In GB 2126231A, vengono descritti benzil-fosfonati alogenati aventi la formula : ;; ;; in cui è CI oppure Br, è C^-C^ alchile e m è 0 ;fino a 5. Questi fosfonati, mentre sono utili per ;rendere resistenti al fuoco certi polimeri, non ;hanno una sufficiente stabilità termica per consentire di venire impiegati in materie plastiche per ;il settore delle costruzioni che vengono lavorate a temperature che arrivano fino a 200°C oppure che superano anche i 200°C. ;Inoltre, nel brevetto giapponese 65-123674, ;vengono descritti composti aventi la formula ;Ar P(=0)(0R )(0R ) nella quale Ar è benzene ;X & o X ;eventualmente sostituito, naftalene , piridina oppure chinolina, event. sostituite i di-Gostituenti essendo scelti , tra gli ;altri, tra alchile, alcossl e bromo, e e sono per esempio (cloro) alchile. Viene indicato che detti composti sono utili quando il gruppo Ar^ contiene sostituenti costituiti da bromo, ma sono difficili da preparare poiché una fosforilazione di composti aromatici pluri-bromurati richiede condizioni drastiche. Come alternativa, si può effettuare la bromurazione dopo una fosforilazione. Ciò è anch'esso indesiderabile poiché è necessario adottare condizioni di bromurazione drastiche che possono parzialmente e/o completamente distruggere la porzione fosfonato. ;Si sono ora trovati certi_arll-fosfonati bromurati che sono facili da produrre e che hanno una stabilità termica sufficiente per venire usati in materie plastiche nel settore ingegneristico. ;La presente invenzione mette a disposizione composizioni di ritardo della fiamma che comprendono: A) un polimero termoplastico oppure termoindurente, e B) almeno un composto avente la formula I: ;; ;; in cui Ar è fenile, naftile oppure è un gruppo avente la formula: ; ;; in cui Y è un legame semplice ;; ;; z è un numero intero compreso tra 5 e 9, e ;R è idrogeno oppure C -C^ alchile preferibilmente metile oppure etile. ;Il substrato di polimero termoplastico oppure termoindurente A) può essere per esempio: ;1.

Copolimeri di stirene di 0(-metilstirene con dieni oppure con derivati acrilici, per esempio, stirene/butadiene, stirene/acrilonitrile , stirene/alchilmetacrilato, stirene/anidride maleica, stirene/butadiene /eti1-acri lato, stirene/acri Ionitrile/me tilacrilato; miscele aventi un'elevata resistenza agli urti ottenute da copolimeri dello sti ;rene e di un altro polimero per esempio stirene/butadiene/stirene, stirene/isoprene/stirene, stirene/etilene/butilene/stirene oppure stirene/etilene/propilene/stirene. ;3. Copolimeri ad innesto di stirene oppure di c(-metilstirene, per esempio, stirene su polibutadiene, stirene su polibutadiene-stirene oppure su polibutadiene-acrilonitrile; stirene ed acrilonitrile (oppure metacrilonitrile) su polibutadiene; stirene ed anidride maleica oppure maleimmide su polibutadiene; stirene, acrilonitrile ed anidride maleica oppure maleimmide su polibutadiene; stirene, acrilonitrile e metil-metacrilato su polibutadiene, stirene ed alchil-acrilati oppure alchil-metacrilati su polibutadiene, stirene ed acrilonitrile su terpolimeri etilene/propilene/diene, stirene ed acrilonitrile su poliacrilati oppure su polimetacrilati, stirene ed acrilonitrile su copolimeri acrilato/butadiene ed anche loro miscele con i copolimeri elencati sotto 5), per esempio le miscele di copolimeri note come polimeri-ABS, -MBS, -ASA oppure -AES. ;4. Polimeri che sono derivati da acidi c(,p-insaturi e da loro derivati per esempio poliacrilati e polimetacrilati, poliacrilammidi e poliacrilonitrili. ;5.

Polifenilen-ossidi e solfuri e miscele o mescolanze di polifenilen-ossidi con polistirene, polimeri ad innesto oppure copolimeri dello stirene, polistirene avente una elevata resistenza agli urti, e copolimeri EPDM con gomme, e miscele di polifenilen-ossidi con poliammidi. ;7. Poliuretani che derivano da polieteri, poliesteri oppure pollbutadieni aventi gruppi ossidrilici terminali da un lato e da poliisocianati alifatici o aromatici dall* altro lato e anche loro precursori (poliisocianati, polioli oppure prepolimeri). It is known that bromine-containing organic compounds can be used as flame retardants in polymer systems. These known bromine-containing flame retardants are traditionally aromatic or cycloaliphatic hydrocarbons, phenols, ethers or polyolbrominated compounds. of antimony, in order to be able to use smaller amounts of the bromine-containing compound, while maintaining a sufficient level of flame retardant activity. A widely used class of flame retardant agents are brominated aryloxy compounds in the ring. However, these known flame retardants have the disadvantage that, upon pyrolysis, they can produce toxic brominated benzodioxins and / or benzofurans. Furthermore, in some cases, the thermal stability and / or UV-stability of such known flame retardants may not be sufficient. In GB 2126231A, halogenated benzyl phosphonates having the formula: ;; ;; where is Cl or Br, is C ^ -C ^ alkyl and m is 0; up to 5. These phosphonates, while useful for making certain polymers fire resistant, do not have sufficient thermal stability to allow them to be used in plastics for the construction sector that are processed at temperatures up to 200 ° C or even over 200 ° C. Furthermore, in Japanese patent 65-123674, compounds are described having the formula; Ar P (= 0) (0R) (0R) in which Ar is benzene; X & o X; optionally substituted, naphthalene, pyridine or quinoline, event. substitute the di-constituents being selected, among others, from alkyl, alkoxy and bromine, and and are for example (chlorine) alkyl. It is indicated that said compounds are useful when the Ar ^ group contains bromine substituents, but they are difficult to prepare since a phosphorylation of pluri-brominated aromatic compounds requires drastic conditions. Alternatively, bromination can be performed after phosphorylation. This is also undesirable since it is necessary to adopt drastic bromination conditions which can partially and / or completely destroy the phosphonate moiety. Certain brominated arll-phosphonates have now been found which are easy to manufacture and which have sufficient thermal stability for use in engineering plastics. The present invention provides flame retardant compositions which comprise: A) a thermoplastic or thermosetting polymer, and B) at least one compound having the formula I: ;; ;; wherein Ar is phenyl, naphthyl or is a group having the formula:; ;; where Y is a simple bond ;; ;; z is an integer between 5 and 9, and; R is hydrogen or C -C4 alkyl, preferably methyl or ethyl. ; The thermoplastic or thermosetting polymer substrate A) can be for example:; 1.

La miscela di reazione viene riscaldata a 140°C fino a che cessa lo sviluppo di etil-bromuro. La miscela di reazione viene raffreddata e il solido viene raccolto mediante filtrazione, viene lavato con o-xilene freddo e quindi con esano freddo e viene essiccato a 80°C fino a peso costante ottenendo così il prodotto sotto forma di una polvere cristallina bianca avente un punto di fusione di 123-124°C e avente la seguente analisi elementare: The reaction mixture is heated to 140 ° C until the development of ethyl bromide ceases. The reaction mixture is cooled and the solid is collected by filtration, washed with cold o-xylene and then with cold hexane and dried at 80 ° C to constant weight thus obtaining the product in the form of a white crystalline powder having a melting point of 123-124 ° C and having the following elemental analysis:
