PROCESS FOR CONTINUOUS PRODUCTION OF HALOGEN-FREE THERMOPLASTIC ELASTOMER COMPOSITIONS Russian patent published in 2017 - IPC C08J3/24 C08J3/20 C08L23/22 C08L51/08 C08L77/00 

Abstract RU 2614277 C2

FIELD: chemistry.

SUBSTANCE: invention relates to thermoplastic elastomer compositions and methods for continuous production of said compositions. continuous method for production of dynamically cured thermoplastic elastomer comprises mixing at first stage of a mixing device of continuous action a thermoplastic resin, a halogen-free elastomer, with polyolefin content of more than 3.5 mol%, which is modified with unsaturated carboxyl compound, and a curing agent. At second stage a curing system is added, which is suitable for use with halogen-free elastomer for dynamic vulcanisation.

EFFECT: invention enables to obtain materials with improved relative elongation at break and ultimate tensile strength.
