Description
ливают в закрытые форлты, смазанные силиконовым л ком, и отверждают при 80°С в течение 40 час.Pour into closed forlts, smeared with a silicone cup, and cure at 80 ° C for 40 hours.
Некоторые свойства полученных полимерных материалов приведены в таблице.Some properties of the obtained polymeric materials are given in the table.
Пример 4. К117 г привитого уретапового олигомера, содержащего 15 вес. ч. КС, добавл ют 5 вес. ч. окиси магни и 16,0 вес. ч. 2,4-ТДИ. Проделывают с этой смесью то же, что и в примерах 2 и 3.Example 4. K117 g grafted uretapova oligomer containing 15 weight. including COP, add 5 wt. including magnesium oxide and 16.0 weight. h. 2,4-TDI. Made with this mixture the same as in examples 2 and 3.
Аналогичные опыты по -синтезу привитых жидких нолиуретановых и их отверждению провод т с полиоксипропилендиолом с молекул рным весом 1000 и 3000 и 2,4-толуилендиизоцианатом . Дл сравнени провод т опыты с жидким полиуретановым олигомером без прививки КС, но с введением перекиси и окиси магни (контрольный опыт). Свойства контрольного образца также приведены в таблицеSimilar experiments on the synthesis of grafted liquid polyurethane and their curing are carried out with polyoxypropylene diol with a molecular weight of 1000 and 3000 and 2,4-toluene diisocyanate. For comparison, experiments were carried out with a liquid polyurethane oligomer without KS vaccination, but with the introduction of peroxide and magnesium oxide (control experiment). Properties of the control sample are also listed in the table.
Предмет изобретени Subject invention
Способ получени эластомеров путем прививки на полимер комплексных соединений 2-метил - 5 - винилпириди-на с галогенидами двухвалентных металлов в присутствии перекнсных соединений, отличающийс тем.The method for producing elastomers by grafting polymer compounds of 2-methyl-5-vinylpyridine with halides of divalent metals in the presence of peer compounds, differing in that.
что, с целью улучшени физико-механических свойств, в качестве полимера используют жидкий полиуретановый олигомер, полученный на основе полиоксипропилендиола с молекул рным весом 1000-3000 и диизоцианатов при соотношении NCO:OH 1:2.that, in order to improve the physicomechanical properties, the polymer used is a liquid polyurethane oligomer obtained on the basis of polyoxypropylene diol with a molecular weight of 1000-3000 and diisocyanates with an NCO: OH ratio of 1: 2.
