METHOD OF PRODUCING VULCANIZATES BASED EMULSION COPOLYMERS OF BUTADIENE WITH ACRYLONITRILES OR STYRENE, OR α-METHYLSTYRENE Russian patent published in 2004 - IPC

Abstract RU 2235739 C2

FIELD: polymer production.

SUBSTANCE: copolymer, prior to supplemented by ingredients, is processed on rolls at 25-45^оС for 60-120 min. Then, accelerators, antioxidants, fillers, plasticizers, vulcanization activators, and sulfur are added. Vulcanization is carried out at 141-143^оС for 40 min. Vulcanizates can be used for manufacturing hoses, sealing means, and other technical-destination rubber items.

EFFECT: increased frost resistance of vulcanizates.
