Abstract

A composition of matter includes a mixture of styrene derivative monomers and methacrylate/acrylate derivative monomers, which have one or more urethane, carbamate, amide, and/or amine functional groups, and initiators, and the compositions are used to achieve composition control of the forming polymer, with the mole fraction of acrylate/methacrylate and styrene moieties in the forming polymer determined preferably by the chemistry and composition of the feeding monomers rather than the viscosity of the monomers.

Claims (32)

1. A composition of matter, comprising:

two or more vinyl-containing monomers consisting of at least two different types of vinyl functional monomers, wherein the two or more vinyl-containing monomers are triethyleneglycol divinylbenzyl ether (TEG-DVBE) and methacrylate derivatives; and

one or more initiators;

wherein the two or more vinyl-containing monomers undergo vinyl conversion to form a composition-controlled cross-linked resin.

2. The composition of matter of claim 1 , wherein the methacrylate derivatives have functional groups selected from a group consisting of:

one or more carbamate groups and/or derivatives;

one or more urethane groups and/or derivatives; and

one or more amine groups and/or derivatives.

3. The composition of matter of claim 1 , wherein the one or more initiators are selected from a group consisting of:

photoinitiator(s) comprising camphorquinone or derivatives,

a combination of cam phorquinone and amine(s) derivatives, phenylpropanedione or derivatives, bisacylphosphine oxide or derivatives, or 1-hydroxycyclohexyl phenyl ketone,

wherein the initiators may be used:

with/without diary iodonium derivatives, and

with/without boryl radicals.

4. The composition of matter in claim 1 , wherein a mole fraction of methacrylate derivatives and TEG-DVBE moieties in the composition-controlled cross-linked resin is determined by the mole fraction corresponding to the methacrylate derivatives and TEG-DVBE.

5. The composition of matter of claim 1 , wherein the composition is used as dental materials that are used with or without fillers as restorative materials, laminate veneers, denture, denture repairing materials, dental adhesives, resin reinforce cements, placement of ceramic restorations, and sealants.

6. The composition of matter of claim 1 , wherein the composition is used in 3D printing.

7. The composition of matter of claim 1 , wherein the composition controlled cross-linked resin is stable against environmental challenges consisting of hydrolysis, corrosion, enzymatic degradation, and bacterial challenges.

8. The composition of matter of claim 1 , wherein the composition is used to make polymers as packaging materials, coating materials and adhesives.

9. The composition of matter of claim 1 , wherein the composition is used to make composition-controlled polymers with alternating methacrylate derivatuves/TEG-DVBE moieties in the chain of the polymers.

10. A composition of matter made by polymerizing the composition of claim 1 with or without fillers using methods comprising of light irradiation and/or heating.

11. The composition of matter of claim 10 , wherein the fillers are selected from a group consisting of:

metal oxide particles, ceramic particles, chitosan, polysaccharide particles, and

the particles are in nano-scale and micro-scale.

12. The composition of matter of claim 10 , wherein the composition is used as dental materials, restorative materials, laminate veneers, denture, denture repairing materials, dental adhesives, inlays and onlays, fixed bridges, implants, resin reinforce cements, placement of ceramic restorations, and sealants.

13. A composition of matter made by polymerizing the composition of claim 1 after the composition infiltrates into pores of porous objects using methods comprising of light irradiation and/or heating.

14. The composition of matter of claim 13 , wherein the porous objects are selected from a group consisting of:

metal oxide, ceramic, chitosan, polysaccharide particles, metal, and wood.

15. The composition of matter of claim 13 , wherein the composition is used as dental materials, restorative materials, laminate veneers, denture, denture repairing materials, dental adhesives, inlays and onlays, fixed bridges, implants, resin reinforce cements, placement of ceramic restorations, and sealants.

16. A composition of matter made by polymerizing the composition of claim 1 to make vinyl-free polymers, polymers with no polymerizable vinyl groups, using methods comprising light irradiation and/or heating.

17. The composition of matter of claim 16 , wherein the composition is used independently or as a component in medical devices, electronic devices, and solar cells.

18. The composition of matter of claim 1 , wherein a copolymer of methacrylate derivatives and TEG-DVBE generates less stress than a bisphenol A glycidyl methacrylate/triethylene glycol dimethacrylate (BisGMA/TEGDMA) copolymer at the same degree of vinyl conversion when initiated by a combination of camphorquinone and amine.
