Description
Известен способ стабилизации иоливинилхлорида (ПВХ) введением в него в качестве стабилизирующей добавки глицеринового эфира р-аминокротоновой кислоты.There is a method of stabilization of irivinyl chloride (PVC) by introducing p-aminocrotonic acid glycerin ester as a stabilizing additive into it.
По предлагаемому способу дл получени синергического эффекта глицериновый эфир р-аминокротоиовой кислоты примен ют совместно с диоктилдималеинатом олова.According to the proposed method, to obtain a synergistic effect, the glycerol ester of p-aminocrotic acid is used in conjunction with tin dioctyldimaleinate.
Пример. Излучепие свойств предлагаемой сииергической смеси проводилось в суспензионном ПВХ марки С-65 в сравнении с термостабилизаторами , выпускаемыми, в промышленности . Концентраци вводимых стабилизаторов , а также смеси стабилизаторов составл ла 0,1 моль/кг ПВХ.Example. The radiation properties of the proposed syergic mixture were carried out in suspension PVC brand C-65 in comparison with heat stabilizers, manufactured in the industry. The concentration of injected stabilizers as well as the mixture of stabilizers was 0.1 mol / kg PVC.
Критерием эффективности вл етс термостабплыюсть порошкообразного ПВХ при температуре 175°С и цветостойкость поливйннлхлоридных пленок после старени их в термостате также при 175°С в течение 3 час.The criterion of efficiency is the thermal stability of powdered PVC at a temperature of 175 ° C and the color resistance of polyvinyl chloride films after aging them in a thermostat also at 175 ° C for 3 hours.
В таблице приведены свойства поливиннлхлоридных композиций с применением предлагаемых стабилизаторов.The table shows the properties of polyvinyl chloride compositions using the proposed stabilizers.
Из данных таблицы видно, что добавление к глицериновому эфиру р-аминокротоновой кислоты дибутилдималеината олова ириводит к резкому увеличению цветостойкости и термостабильности (синергический эффект) композиции ПВХ с 70 мин (комиозици 2) до 140 мин (комиозици 4) при равных мол риых концентраци х.The data in the table show that the addition of dibutyldimaleate tin to glycerol ester of p-aminocrotonic acid and leads to a sharp increase in color stability and thermal stability (synergistic effect) of the PVC composition from 70 minutes (comyose 2) to 140 minutes (comyotation 4) with equal molar concentrations.
