Abstract
The phenolic resin curatives used as a curative in thermoplastic elastomers are attributed with staining of painted surfaces which physically contact the thermoplastic elastomers. When the phenolic resin curatives are esterified (e.g., acetylated, tosylated, silylated or phosphorylated) before use as a curative, the amount of staining is reduced or staining is eliminated.
