General description

N,N,N′,N′′,N′′-Pentamethyldiethylenetriamine (PMDETA) is an amine-based monomer compound that plays a crucial role in the field of polymers, particularly in the synthesis of TRPs- thermoresponsive polymers. PMDETA acts as a versatile ligand or catalyst in various polymerization reactions. It forms complexes with transition metals, which are utilized in the production of specialty polymers, block copolymers, and polymers with modified properties. These polymers find applications across a broad range of industries, including thermoplastics, elastomers, and coatings. When incorporated into the polymer structure, PMDETA helps impart thermoresponsive behavior to the final product, enabling reversible changes in solubility, conformation, or other physical properties in response to temperature variations. This makes PMDETA a valuable component in the synthesis and design of TRPs, which find uses in areas such as drug delivery systems, smart materials, and responsive coatings.

Application

N,N,N′,N′′,N′′ Pentamethyldiethylenetriamine can be used as:
  • A catalyst in the synthesis of multifunctional silicone acrylate prepolymers for use in UV-curable coatings.
  • A multifunctional initiating and cross-linking agent in the synthesis of polyacrylamide hydrogels. It improves the mechanical properties of the hydrogels, such as toughness and resilience, without compromising their biocompatibility.
  • An organocatalyst in ring-opening polymerization (ROP) of trimethylene carbonate. This catalyst can be easily removed after the reaction compared to metal catalysts.
  • A catalyst along with CuBr to synthesize a series of side-chain azobenzene poly(meth)acrylates via the atom transfer radical polymerization(ATRP) technique.
  • An initiator to grow polystyrene chains to prepare polyolefin-polystyrene copolymers.

Polyolefins (POs) are the most abundant polymers. However, synthesis of PO-based block copolymers has only rarely been achieved. We aimed to synthesize various PO-based block copolymers by coordinative chain transfer polymerization (CCTP) followed by anionic polymerization in one-pot via conversion

Articles

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.

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 radical polymerization.

Protocols

We presents an article featuring procedures that describe polymerization of methyl methacrylate and vinyl acetate homopolymers and a block copolymer as performed by researchers at CSIRO.

We present an article about RAFT, or Reversible Addition/Fragmentation Chain Transfer, which is a form of living radical polymerization.

Polymerization via ATRP procedures demonstrated by Prof. Dave Haddleton's research group at the University of Warwick.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
