Abstract
1. Способ получения вспенивающихся гранул стирольного полимера методом прямого насыщения расплава полимера вспенивающим агентом в системе статических смесителей, включающий в себя подачу в расплав добавок и последующую грануляцию полученного расплава в условиях, предотвращающих заметное вспенивание гранул, отличающийся тем, что в качестве комплексной добавки используется воск с температурой каплепадения более 70°C в количестве от 0,1 до 2,5 мас.% на гранулы вспенивающегося стирольного полимера, имеющий следующую общую формулу ! (-CHR1-CHR2-)x, ! в которой R1, R2 в каждом случае независимо обозначают H, R' или группу -OH, группу -COOH, группу -C=O, группу -O-CO-CH3, группу -COOR', где R' представляет собой радикал с 1-20 атомами углерода, x представляет целые числа в интервале от 10 до 300. ! 2. Способ по п.1, отличающийся тем, что в качестве воска используют окисленный или неокисленный полиэтиленовый воск. ! 3. Способ по п.1, отличающийся тем, что в качестве дополнительной добавки используют гексабромциклододекан. 1. A method of producing expandable styrene polymer granules by direct saturation of the polymer melt with a blowing agent in a static mixer system, comprising adding additives to the melt and subsequent granulation of the obtained melt under conditions that prevent noticeable foaming of the granules, characterized in that wax is used as a complex additive with a dropping point of more than 70 ° C in an amount of from 0.1 to 2.5 wt.% on the granules of an expandable styrene polymer having the following general formula! (-CHR1-CHR2-) x,! in which R1, R2 in each case independently represent H, R 'or a group -OH, a group -COOH, a group -C = O, a group -O-CO-CH3, a group -COOR', where R 'represents a radical with 1 -20 carbon atoms, x represents integers in the range from 10 to 300.! 2. The method according to claim 1, characterized in that the wax used is oxidized or non-oxidized polyethylene wax. ! 3. The method according to claim 1, characterized in that hexabromocyclododecane is used as an additional additive.
