Bisphenol A glycerolate dimethacrylate, 80%

Product Introduction

Bisphenol A Glycerolate Dimethacrylate (Bis-GMA) is a high-molecular-weight, bifunctional methacrylate monomer widely investigated for crosslinked polymer and resin systems.

The molecule contains two methacrylate groups that can undergo free-radical polymerization, together with hydroxyl-containing side chains and a rigid bisphenol A-derived aromatic backbone. This structure contributes to the formation of crosslinked polymer networks with high rigidity and is particularly important in resin-based dental materials.

Bis-GMA is widely associated with dental composite and dental sealant formulations and is also investigated in UV-curable coatings, adhesives, polymer composites, and functional resin systems.

Mechanism / Principle

Bis-GMA undergoes free-radical polymerization through its two methacrylate double bonds.

When exposed to an appropriate radical initiator or photoinitiator system, the carbon–carbon double bonds of the methacrylate groups react to form growing polymer chains. Because Bis-GMA contains two polymerizable groups, it can contribute to the formation of a three-dimensional crosslinked polymer network.

In dental resin systems, Bis-GMA is commonly combined with other monomers such as TEGDMA, together with photoinitiators, fillers, and other formulation components. The resulting network can be evaluated for degree of conversion, mechanical properties, polymerization shrinkage, water interaction, and long-term stability.

Key Research Applications

1. Dental Resin Composites

Bis-GMA is an important resin monomer for research and formulation of resin-based dental composites. Its rigid aromatic structure and two methacrylate groups make it suitable for developing crosslinked dental resin matrices used with inorganic fillers.

2. Dental Adhesives and Bonding Systems

Bis-GMA can be incorporated into dental adhesive and bonding formulations to develop polymerizable resin systems for bonding research. Its bifunctional structure enables formation of crosslinked polymer networks after curing.

3. Dental Restorative Materials

Bis-GMA is widely investigated as a resin component in restorative dental materials, including composite restorative systems and related light-curable formulations. Researchers can study its influence on polymerization, mechanical properties, shrinkage, and durability.

4. Dental Sealants

Bis-GMA is relevant to the development and investigation of resin-based dental sealants. Its polymerizable methacrylate groups allow it to participate in light- or chemically initiated curing systems.

5. Photopolymerizable Dental Materials

Bis-GMA can be combined with suitable photoinitiators to formulate light-curable dental resin systems. Research may focus on curing efficiency, degree of conversion, polymerization kinetics, and the relationship between formulation composition and final material properties.

6. Crosslinked Polymer Materials

The two methacrylate groups allow Bis-GMA to participate in crosslinking and network formation. It can therefore be used in polymer research investigating network structure, mechanical performance, thermal properties, and dimensional stability.

7. UV-Curable Coatings and Adhesives

Bis-GMA can be investigated in UV-curable resin systems for coatings, adhesives, and other functional polymer formulations. Its multifunctional methacrylate structure supports rapid radiation-induced polymerization and network formation.
