The present invention provides a polymer composition comprising a polymer and an antioxidant comprising a diarylamine-based compound represented by General Formula (1): where, in General Formula (1), Aand Aeach independently represent a Cto Carylene group which may have a substituent, and Aand Aeach independently represent an organic group having a cyclic imide structure which may have a substituent.

Polymer composition containing diarylamine-based compound

The present invention provides a diarylamine-based compound represented by General Formula (1): (where Aand Aeach independently represent a Cto Carylene group which may have a substituent, and Aand Aeach independently represent an organic group having a cyclic imide structure which may have a substituent).

Diarylamine-based compound, anti-aging agent, and polymer composition

A nitrile rubber composition containing a carboxyl group-containing nitrile rubber and an allylamine-based polymer which contains units expressed by the following general formula (1) is provided. (In the general formula (1), R, R, and Rrespectively independently are one selected from a group including a hydrogen atom, alkyl group containing 1 to 4 carbon atoms which may have substituents, aryl group containing 6 to 12 carbon atoms which may have substituents, and halogen atom.).

Nitrile rubber composition and cross-linked rubber

A nitrile copolymer latex composition containing a latex of a nitrile copolymer rubber (A) having &#x3b1;,&#x3b2;-ethylenically unsaturated nitrile monomer units in 10 to 75 wt %, conjugated diene monomer units in 5 to 89.9 wt %, and cationic monomer units and/or monomer units able to form cations in 0.1 to 20 wt %, an inorganic filler (B) having an aspect ratio of 30 to 2,000, and a plasticizer (C) having an SP value by the HOY method of 8 to 10.2 (cal/cm), wherein a content of said plasticizer (C) is 0.1 to 200 parts by weight with respect to said nitrile copolymer rubber (A) as 100 parts by weight is provided.
