Abstract
Abstract A highly extended,unsaturated polyester resin syrup composition mixture comprising unsaturated polyester resin syrup, basic aluminum chloride and non-reinforcing extender material which is substantially non-reactive with the resin syrup and the basic aluminum chloride. The composition mixture may be used to prepare a shaped article comprised of the cured, cross-linked composition. The article is prepared by first forming a first component comprising unsaturated polyester resin syrup and non-reinforcing extender material and a second component comprising a solution of basic aluminum chloride and non-reinforcing extender material. The two components are mixed together to yield the composition mixture which possesses a viscosity low enough to be worked with conventional apparatus. The composition mixture is then shaped into the configuration of the desired article, allowed to cure and, if necessary, allowed to set. The extender material may be selected such that the resulting composition exhibits excellent structural strength and fire properties.
