The present invention relates to modified polyetherimide resins. Such resins contain high density polyethylene in an amount effective to raise the melt viscosity of the polyetherimide and reduce the tendency of the resin to stick to molds during injection molding.

Modified polyetherimide resins

The present invention relates to a foamable polyetherimide resin. These foamable polyetherimides have an effective amount of a chemical blowing agent which decomposes at a temperature equal to or greater than the glass transition temperature of the polyetherimide resin and does not have an adverse effect on the polyetherimide.

Foamable polyetherimide resin formulation

A stable and non-separating catalyst paste, reactive into a polyester system, said paste comprising a diacyl peroxide; a plasticizing amount of a vinyl-reactive di(hydroxyloweralkoxyalkyl) fumarate plasticizer; a finely divided mineral filler, e.g., calcium carbonate, in an amount sufficient to prevent the composition from physically separating into its components; the remainder, if any, being water.

Storage stable reactive peroxide paste composition

The foaming of resinous insulating materials under vacuum is substantially reduced by adding to the material a polydiene having primarily vinyl unsaturation.

Antifoaming resin compositions

A filled, two-part plastic-producing system is described. This system is based on the use of unsaturated polyester resin and a benzoyl peroxide paste curing agent. By modification of either or both parts of the system, its utility is greatly enhanced. Further a cement composition useful in a filled two-part grout-producing system is described.

Filled, two-part plastic-producing system

Storage stable, fluent, ambient temperature polymerizable resin compositions comprise:

Storage stable polyester monomer compositions with inhibitor, promoter,

A stable and non-separating catalyst paste comprising a diacyl peroxide; a minor proportion of water; a finely divided calcium carbonate in an amount sufficient to prevent the composition from physically separating into its components; the remainder, if any, being a chemically inert plasticizer.
