Пластификаторы ввод т на скоростном смесителе ( об/мин, врем смешени 10 мин), с последующими гомогенизацией в расплаве на экструдере с диаметром черв ка 30 мм и длиной , равной 15Д, и гранул цией.Example 1 -10. Pentaplast-based compositions are prepared with a viscosity of 1.6 dl / g, stabilized with a mixture of 0.34 wt. % bisalcofen BP byc- (5-methyl-3-gregbutyl-2-hydroxyphenyl) methane and 1% epoxy resin, and 2-25 weight. % plasticizers. Plasticizers were introduced at a high-speed mixer (rpm, mixing time 10 minutes), followed by homogenization in the melt on an extruder with a screw diameter of 30 mm and a length of 15D, and granulation.

В табл. 3, 4 приведены сравнительные свойства предлагаемых композиций и известных композиций на основе производных фталевой и себациновой кислот, а именно: дибутил-, диоктил- и дидодецилфталата соответственно (ДБФ, ДОФ и ДДФ), дибутил- н диоктилсебацинатаthe same extruder, but through a flat-slot head 1i 190-210 ° C. The thickness of the samples for determining the frost resistance according to GOST 5960-51 was 0.5 mm. Samples for other types of tests are obtained by pressing at 190–200 ° C and a pressure of 100 kgf / cm. The tests were carried out using 00 procedures TU 6-05-1693-74. The results are shown in Table. i and 2. In table. 3, 4 shows the comparative properties of the proposed compositions and known compositions based on phthalic and sebacic acid derivatives, namely: dibutyl, dioctyl and diddecylphthalate, respectively (DBP, DOP and DDP), dibutyl dioctyl sebacate
