Abstract
Unsaturated polyester resin compositions contain an amine accelerator of formula ##STR1## wherein R.sup.1 and R.sup.2 are alkyl, hydroxyalkyl or carboxyalkyl groups and R.sup.3, R.sup.4 and R.sup.5 are alkyl, aralkyl, cycloalkyl, alkoxy or halogen groups.
Claims5
An unsaturated polyester resin composition which comprises an unsaturated polyester, a soluble cobalt salt, an amine accelerator having the formula ##STR3## where R.sup.1, R.sup.2 are selected from the radicals alkyl, hydroxyalkyl and carboxy alkyl groups and R.sup.3, R.sup.4 and R.sup.5 are selected from the radicals alkyl, aralkyl, cycloalkyl, alkoxy and halogen groups, and a peroxy initiator that is accelerated by said amine.
