Description
растворитель и сушат олигомер при 40°С в вакууме.solvent and the oligomer is dried at 40 ° C. in vacuo.
Обработанный таким образом олигопиперилен содержит 1,25 мае. % карбоксильных групп, определ емых титрованием. В ИК-спек ,тре полученного продукта по вл етс полосаThe oligopiperylene treated in this manner contains 1.25 May. % of carboxyl groups determined by titration. In the IR spectrum, the resulting product appears the band
поглощени 1720 см absorption 1720 cm
что также указывает на наличие карбоксильных групп в олигомере . Молекул рна масса после обработки озоно-кислородной смесью 2050.which also indicates the presence of carboxyl groups in the oligomer. Molecular weight after treatment with ozone-oxygen mixture 2050.
Пример 2. Аналогично примеру 1 за исключением того, что исходный олигопиперилен вз т с молекул рной массой 6560 пропускают озоно-кислородную смесь 2,8 ч.Example 2. Analogously to Example 1, except that the initial oligopiperylene was taken with a molecular weight of 6560 and the ozone-oxygen mixture was passed through 2.8 hours.
Обработанный таким образом олигопиперилен содержит 1,0 мае. % карбоксильных групп. Молекул рна масса 3250.Oligopiperylene treated in this manner contains 1.0 May. % carboxyl groups. Molecular weight 3250.
В табл. 1 приведены результаты испытани образцов .резиновых смесей на клейкость.In tab. 1 shows the test results of samples of rubber compounds for tackiness.
