Publication number: 20080262187Abstract: This invention provides a blend which comprises (i) at least one aromatic primary diamine, with which has been blended a color-minimizing amount of at least one N,N-dmydrocarbylhydroxylamine, wherein the aromatic primary diamine is in the form of one benzene ring having two primary amino groups on the ling, which amino groups are meta or para relative to each other, and in which each position ortho to a primary amino group bears an alkyl group, and (ii) at least one aromatic secondary diamine having a Gardner color number no more than about 7, wherein said aromatic secondary diamine either is in the form of one benzene ring having two secondary amino groups on the ring, or is in the form of two benzene rings connected by an alkylene bridge and having one secondary amino group on each ring. Optionally, at least one N,N-dihydrocarbylhydroxylamine has been blended with the aromatic secondary diamine.Type: ApplicationFiled: December 21, 2006Publication date: October 23, 2008Applicant: ALBEMARLE CORPORATIONInventors: John Y.
