(54) PLBIONOM&RNY KOPOLYESTER KYSELINY TEREFTÁLOVEJ A 5-SJLFOIZOFTÁLOVEJ(54) PLBIONE & RNY KOPOLYESTER OF TEREFTAL AND 5-SALPHONIZOFTAL
Vynález aa týká pleionomérneho kopolyeateru kyseliny tereftálovej a 5-sulfoizoftálovej, ktorý sa uplatňuje ako pomocný prípravok pře antistatická úpravu a úpravu umožňujúcu lahkú vyprateinost Spiny.The invention aa relates to a pleionomeric copolyeater of terephthalic acid and 5-sulfoisophthalic acid, which is used as an adjunct to antistatic treatment and to allow for the easy recovery of Spina.
Doteraz sa připravovali len polymérne kopolyestery kyseliny 5-sulfoizoftálovej použité priamo ako vláknotvorné materiály napr. tesil 31. Oligomérne kopolyestery pře úpravu polyesterových vlákien doteraz připravené neboli.To date, only polymeric copolyesters of 5-sulfoisophthalic acid used directly as fiber-forming materials e.g. tesil 31. Oligomeric copolyesters have not previously been prepared for the treatment of polyester fibers.

Uvedené produkty sú vhodné nielen pre antistatické úpravy a úpravy umožňujúce Íahkú vyprsteínost Spiny, ale tiež pre nehoříavú úpravu, najma účinným viazaním kvartérnych foefóaiových zlúčenín, ako aj vyfarbovania pomocou kanónových ferbív a antimikrobiálnej úpravy aplikáciou biocídnych prostriedkov typu kvartérnych amóniových tenzidov.Said products are suitable not only for antistatic treatments and those which allow light spinning of Spina, but also for non-flammable treatment, in particular by efficient binding of quaternary phosphoium compounds, as well as by canon-staining and antimicrobial staining by applying biocidal agents such as quaternary ammonium surfactants.
Sposob přípravy pleionomérneho kopolyesteru kyseliny tereftálovej a 3-sulfoizoftáloveJ je v 3alšom popísáný v prikledoch prevedenia bez toho, že by sa výhradně na tieto typy přípravy vzlahoval.The process for preparing the pleionomeric copolyester of terephthalic acid and 3-sulfoisophthalic acid is described in the following in the examples without being solely related to these types of preparation.
Příklad 1Example 1
Do polykondenzačného reaktora sa dá 1000 g dimetyltereftalátu, 0,33 g octanu manganatého a 641 g etylénglykolu. Potom sa kotol zahřeje na 170 °C a počae 120 minut sa teplota e1000 g of dimethyl terephthalate, 0.33 g of manganese acetate and 641 g of ethylene glycol are added to the polycondensation reactor. The boiler is then heated to 170 ° C and the temperature is e
reaktora nechá stúpnuí na 250 °C, pričom postupné vydestilováva metanol a etylénglykol. Potoř sa přidá 844 g 33 Λ-ného roztoku bis/hydroxyetyl/esteru aodnej soli kyseliny 5-sulfoizoftálovej /polykondenzačnej zložky/ 54 ml kysličníka germaničitého, 2,8 g chloridu sodného a 0,3 ml trifenyl fosfátu. Zahrieva sa 3alžích 5 až 55 minút za zapojenie vakua, pričom vzniká produkt charakterizovaný limitným viskozitným číslom 6,203 až 13,540 ml/g a obsahom 15 » mol. vbudovanej kyseliny 5-sulfoizoftálovej, teplota topenia, v závislosti na dlžke reakčnej doby, je v rozmedzi 65,3 až 231,6 °C.The reactor is allowed to rise to 250 [deg.] C. while methanol and ethylene glycol are distilled off successively. 844 g of a 33 Λ solution of bis (hydroxyethyl) ester and 5-sulfoisophthalic acid / polycondensation component / 54 ml of germanium oxide, 2.8 g of sodium chloride and 0.3 ml of triphenyl phosphate are then added. Heat for 3 minutes for 5 to 55 minutes under vacuum to give a product characterized by a viscosity limit of 6,203 to 13,540 ml / g and a content of 15 »mol. 5-sulfoisophthalic acid incorporated, the melting point, depending on the length of the reaction time, is in the range of 65.3 to 231.6 ° C.
