[0168] Measurement methods:

[0169] The RDB content (residual double bond content) in % is determined by the following FT-IR measurement: AVATAR360 Thermo Nicolet FT-IR spectrometer IR instrument records the hydrogenated nitrile-diene-carboxylate copolymer before, during and after hydrogenation IR Spectrum afterward. For this purpose, hydrogenated nitrile-diene-carboxylate copolymers in monochlorobenzene were applied to NaCl flakes, dried as films and analyzed. The degree of hydrogenation was determined by FT-IR analysis according to ASTM D 567095 method.

[0170] The Mooney viscosity values ​​(ML1+4 at 100° C.) are determined in each case by means of a shear disc viscometer according to ASTM D1646-07.

[0171] Molecular weights are determined by gel permeation chromatography (GPC). A modular system was used consisting of a Shodex RI-71 differential refractometer, an S 5200 autosampler (from SFD), a column thermostat (ERC-125), a Shimadzu LC 10AT pump, and Column pack of ...

Abstract

The present invention relates to hydrogenated nitrile-diene-carboxylate copolymers, their production, curable mixtures comprising hydrogenated nitrile-diene-carboxylate copolymers and their production, and hydrogenated nitrile-diene-carboxylate-based Cured materials of ester copolymers and their use in belts.

Description

technical field [0001] The present invention relates to hydrogenated nitrile-diene-carboxylate copolymers, their production, curable mixtures containing hydrogenated nitrile-diene-carboxylate copolymers and their production, and also hydrogenated nitrile-diene-based - Vulcanizates of carboxylate copolymers and their use in belts. Background technique [0002] The term nitrile-butadiene copolymer (nitrile rubber, also referred to simply as "NBR") is understood in the context of this application to mean that it is at least one α,β-ethylenically unsaturated nitrile, at least one A rubber of a copolymer, terpolymer or tetrapolymer of a conjugated diene and optionally one or more additional copolymerizable monomers. [0003] The term hydrogenated nitrile-butadiene copolymer ("HNBR") is understood to mean the corresponding copolymer, terpolymer or tetramer. [0004] Over the years, both NBR and HNBR have established themselves in the field of specific elastomers. They have an ...
