Title:
COMPOSITION COMPRISING NITROXIDE, ACCELERATOR AND OPTIONALLY FREE RADICAL INITIATOR
Document Type and Number:
Japanese Patent JP2007327063
Kind Code:
A
Abstract:
To provide a scorch retarder, in order to improve scorch resistance and crosslinking density without adverse influence on the crosslinking time, which inhibits too early crosslinking (scorch) before the crosslinking of a thermoplastic composition and/or an elastomer composition with a peroxide or an azo compound, and to provide a crosslinkable composition and the crosslinking method.
A scorch-delaying composition comprises a nitroxide and a promoter selected from the group (P) consisting of compounds containing at least a double bond and being bifunctional or polyfunctional. The weight ratio of the nitroxide to the amount of the existing promoter is 1:0.2-1:5, or 1:0.5-1:2 preferably.
