Description

пропилкарбоксиметилметакрилат, р-цианэтилметакрилат ). Отсутствие подвулкгнизации резиновых смесей при удовлетворительной скорости вулканизации, а также высока  температуро- и теплостойкость резин позвол ют использовать предла гаемую композицию в издели х, paf5oтающих при повышенных температурах. Примеры 1-3. В этих примерах используют смеси на основе сополимера бутадиена и изопропилкарбоксиметилметакрилата в соотношении 100:10 (БЭФ-10Н). Состав смеси и характеристика вулканизатов на ее основе приведены в табл. 1, в которой дл  сравнеСоставы смесей и св полученных ни  приведены также состав и свойства известной смеси на основе БЭФ-10И с глицерином в качестве активатора и свойства вулканизатов на ее основе. Примеры 4-5. Состав композиции и характеристику полученных вулканизатов на ее основе приведены в табл.2, в которой дл  сравнени  приведены также состав и свойства известной смеси на основе бутадиена и изопропилкарбоксиметилметакрилата - 100, гидроокиси кальци  - 10, глицерина - 2,5, серы - 1 , сантокюра - 0,7, окись цинка - 0-2 и свойства вулканизатов на ее основе. Таблица 1 вулканизатов, основеpropyl carboxymethyl methacrylate, p-cyanoethyl methacrylate). The lack of sub-vulcanization of rubber compounds at a satisfactory vulcanization rate, as well as the high temperature and heat resistance of rubber, make it possible to use the proposed composition in articles paf5o at elevated temperatures. Examples 1-3. In these examples, mixtures based on a copolymer of butadiene and isopropylcarboxymethyl methacrylate in a ratio of 100: 10 (BEF-10H) are used. The composition of the mixture and the characteristics of the vulcanizates based on it are given in table. 1, in which, for comparison, the composition of the mixtures and the resulting mixture also shows the composition and properties of a known mixture based on BEF-10I with glycerol as an activator and the properties of vulcanizates based on it. Examples 4-5. The composition and characteristics of the obtained vulcanizates based on it are given in Table 2, in which, for comparison, the composition and properties of the known mixture based on butadiene and isopropylcarboxymethyl methacrylate - 100, calcium hydroxide - 10, glycerol - 2.5, sulfur - 1, santhoice - 0.7, zinc oxide - 0-2 and properties of vulcanizates based on it.
