WHAT ARE MALONATE MONOMERS?

Our methylene malonate monomers offer exciting new routes to improving the fundamental performance attributes of adhesives, coatings, sealants and other polymers. These unique monomers will help you create new polymer architectures and take advantage of efficient, sustainable polymerization mechanisms.

ANIONIC POLYMERIZATION

 

Our methylene malonate monomers are highly electron deficient, which enables a unique anionic polymerization mechanism that takes place at ambient temperature while offering:

  • The ability to tune molecular weight by adjusting initiator concentration
  • Basic substrate or surface initiation
  • Stable polyolefin backbone
  • The ability to use a broad range of benign initiators as a primer or to promote emulsion or solvent polymerization
  • Living polymerization
  • The ability to sequentially add monomers to form random and block copolymers
  • Crosslinking of 2K systems

VERSATILE POLYMER CHEMISTRY

Methylene malonates are 1,1-disubstituted alkenes in which the central alkene unit bonds to two carbonyl groups, resulting in electron withdrawing characteristics. As a result, these malonates provide a number of alternate routes to polymerization and functionalization.

  • Methylene malonates polymerize via anionic and Michael addition mechanisms as well as conventional free radical polymerization.
  • Multi-functional variants of methylene malonates can be easily synthesized through a transesterification process to form oligomeric crosslinkers.
Asset 1 The highly reactive, electron deficient olefin promotes fast polymerization at room temperature. R can impart beneficial characteristicssuch as flexibility, rigidity, crystallinity,hardness, chemical compatibility andtemperature resistance.
Asset 2 The linking group brings two or more methylene groups into one molecule.Crosslinking can increase strength andthermal and chemical resistance. R can impart beneficial characteristicssuch as flexibility, rigidity, crystallinity,hardness, chemical compatibility andtemperature resistance.
