The Progress in Development of Dental Restorative Materials
The Progress in Development of Dental Restorative Materials
Polymer Analysis in Materials Science
Scientists at Sigma-Aldrich® routinely determine number-average molecular weight (Mn) by 1H NMR end-group analysis for polymers having Mn values under 3,000.
Innovative Materials for Glass Ionomer Cements (GICs): Dental Applications
Innovation in dental restorative materials is driven by the need for biocompatible and natural-appearing restoration alternatives. Conventional dental materials like amalgam and composite resins have inherent disadvantages.
High-Purity Monomers & Polymers for Ophthalmic Applications
We offer a continuously expanding selection of high-purity monomers and polymers for ophthalmic applications, along with a full range of initiators, crosslinkers, dyes, and solvents.
Continuous Flow Manufacturing for Monomer Synthesis
The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear
A Micro Review of Reversible Addition/Fragmentation Chain Transfer (RAFT) Polymerization
We presents an article about a micro review of reversible addition/fragmentation chain transfer (RAFT) polymerization. RAFT (Reversible Addition/Fragmentation Chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to
ATRP Ligands and Initiators for the Clean Synthesis of Functional Polymers
Atom transfer radical polymerization (ATRP) has emerged as one of the most successful synthetic techniques for the preparation of polymers with predetermined molecular weights, narrow molecular weight distributions, and high degrees of chain end functionalities.
RAFT: Choosing the Right Agent to Achieve Controlled Polymerization
Find reversible addition–fragmentation chain transfer(RAFT) polymerization process, classes of RAFT agents & applications.
