FIELD: polymer production. ^ SUBSTANCE: copolymer, prior to supplemented by ingredients, is processed on rolls at 25-45 for 60-120 min. Then, accelerators, antioxidants, fillers, plasticizers, vulcanization activators, and sulfur are added. Vulcanization is carried out at 141-143 for 40 min. Vulcanizates can be used for manufacturing hoses, sealing means, and other technical-destination rubber items. ^ EFFECT: increased frost resistance of vulcanizates. ^ 1 tbl, 16 ex |
