Abstract
Abstract A novel amine-promoted, peroxide-cured polyester composition which can be utilized at low temperatures, e.g. 25° to 50° F., but which will not react at an excessively rapid rate should the amine be added to the curing agent before the curing agent is mixed with the polyester. The preferred system comprises, in addition to the polyester resin and peroxide curing agent, (a) an organoalkanolamine and (b) a hydrated inorganic filler on which the amine is distributed.
