    摘要: Method of promoting the cure of unsaturated polyester resins with a peroxide initiator at room or below room temperatures (low temperatures) by including as a promoter N,N-dimethyl-p-toluidine (DMPT) or a blend of DMPT and N,N-dimethyl-m-toluidine (DMMT) and to the polyester composition containing such promoter. The use of the DMPT or blend of DMPT and DMMT as a promoter provides a fast cure at low temperatures without loss of physical properties of the cured resins.

    摘要: A method for reducing the volatile organic content of coating compositions wherein first, the ketimine of acetone is formed by reacting acetone and a ketimine having the formula ##STR1## wherein n is 1 to 4, R.sub.1 and R.sub.2 may be alkyl aryl, cycloaliphatic or substituted alkyl, aryl, or cycloaliphatic group. R.sub.1 and R.sub.2 may be the same or different, with the proviso that R.sub.1 and R.sub.2 are not both CH.sub.3. R.sub.3 is an aliphatic, aromatic arylaliphatic or cycloaliphatic group, which may also contain O, N, S or Si. The ketimine of acetone is subsequently reacted with at least one isocyanate functional crosslinking resin.
