Abstract
A filler material of a thermoset resin of a diacid/polyol, such as PGS is provided. The filler useful in forming composites, such as those in which the filler and a resin matrix are of the same material to provide a homogenous polymeric composition. Composites in which at least one of the matrix, the filler or both are PGS are also provided. Methods of forming such filler materials and composites are also disclosed. The composites allow extrusion process to form articles from materials that would not otherwise be capable of being extruded.
Claims31
A filler material comprising a thermoset resin of a polymer that comprises a condensation reaction product of a diacid and a polyol and having a particle size between 0.5 and 1000 microns.
An article comprising a composite of a resin matrix and a thermoset filler, the thermoset filler having a particle size between 0.5 and 1000 microns, wherein the resin matrix, thermoset filler, or both of the resin matrix and thermoset filler comprise PGS, the thermoset filler being present as about 10% by weight to about 90% by weight of the composite.
An article comprising a composite of a thermoset filler having a particle size less than 250 microns in a cross-linked resin matrix, wherein the resin matrix and thermoset filler both comprise PGS, the thermoset filler is present from about 40% by weight to about 70% by weight of the composite, the resin matrix has a molecular weight of 5,000-50,000 Da. prior to cross-linking, the thermoset filler has a cross-link density of cross-link density of about 0.07 mol/L or greater, and the thermoset filler and the resin matrix each have a molar ratio of glycerol to sebacic acid in the range of 0.7:1 to 1.3:1.
An article comprising a composite of a resin matrix and a thermoset filler, the thermoset filler having a particle size between 0.5 and 1000 microns, wherein the resin matrix and the thermoset filler both comprise the same material, the thermoset filler being present as about 10% by weight to about 90% by weight of the composite.
A method of forming a filler material comprising
- providing a thermoset comprising PGS;
- forming particles of the thermoset material having a particle size between 0.5 and 1000 microns.
A method of forming an article comprising
- providing a composite comprising a PGS resin matrix and a thermoset PGS filler material having a particle size between 0.5 and 1000 microns, wherein the thermoset PGS filler material is at least 50% by weight of the composite;
- forming the composite into a predetermined shape;
- and
- curing the PGS resin matrix.
