Abstract
The disclosure relates to thermosetting reinforced resin compositions and methods of forming boards, sheets and/or films using of porous particulates impregnated with embedded live monomer and/or oligomer and/or polymer configured to partially leach out a functional terminal end of the live monomer and/or oligomer and/or polymer and react with a cross-linking agent and photoinitiated polymer radicals to form a reinforced board, sheet and/or film of hybrid interpenetrating networks.
Claims23
A method of forming a reinforced thermoset board, film sheet or an article of manufacture comprising:
- a. providing a suspension composition comprising a dispersed phase comprising:
- i. plurality of primary porous particulates impregnated with a monomer, an oligomer, a polymer or a combination comprising the foregoing, wherein the monomer, oligomer, polymer or a combination thereof has a first terminal end coupled to the porous particulate and a functional second terminal end;
- ii. a continuous phase, comprising:
- multifunctional acrylate monomer, oligomer, polymer or their combination;
- a cross-linking agent and a radical photinitiator, wherein the monomer, oligomer, polymer or their combination impregnated in the porous particulates is partially soluble in the continuous phase or is thermodynamically incompatible with a material forming the particulates;
- b. leaching a portion of the monomer, oligomer, polymer or a combination thereof from the porous particulates;
- c. contacting the leached monomer, oligomer, polymer or a combination thereof with the cross-linking agent, wherein the cross-linking agent is configured to activate the radical photoinitiator;
- d. using the activated the radical photoinitiator, exposing the continuous phase to electromagnetic radiation configured to initiate radical formation in the multifunctional acrylate monomers, oligomers, polymers or their combination;
- and
- e. reacting the monomer, oligomer or a combination thereof from the porous particulates with the cross-linking agent and the radicalized multifunctional acrylate monomers, oligomers, polymers or their combination.
A suspension composition comprising:
- a. a dispersed phase comprising a plurality of porous particulates impregnated with embedded monomer, oligomer, or a combination comprising the foregoing, wherein the monomer, oligomer or a combination thereof has a first terminal end coupled to the porous particulate and a second, functional terminal end, wherein the monomer, oligomer, polymer, or their combination that is operably coupled to the porous particulates are entirely embedded within the particulates and configured to leach out of the porous particulate at a temperature of between about 60° C. and about 150° C.;
- and
- b. a continuous phase comprising:
- multifunctional acrylate monomer, oligomer, polymer or their combination;
- a cross-linking agent;
- and a radical photinitiator,
- wherein the monomer, oligomer, polymer or their combination impregnated in the porous particulates is partially soluble in the continuous phase and/or is thermodynamically incompatible with a material forming the particulates.
