Loveland, OH – June 27, 2018—Sirrus, Inc., the developer of a novel electron deficient monomer platform, is pleased to announce that it has been issued its 50th global patent, all relating to its 1,1-dicarbonyl substituted alkene monomer technology.

The company’s intellectual property portfolio includes a broad range of both composition of matter and method patents—the first of which was awarded in December 2013. “The velocity of our global patent issuances has been remarkable,” says Sirrus SVP of Technology, Jeff Sullivan. “It’s a testament to the talent and innovation of our team, creative problem solving and disruptive attributes of our technology platform.”

1,1-dicarbonyl substituted alkenes are electron deficient monomers that polymerize with very little to no energy input. Also, being disubstituted affords the ability to vary functional groups offering greater control of polymer properties.

Sirrus’s core monomer and macromer products—Chemilian™ and Forza™—have near-term applications in adhesives, sealants and coatings. Other promising applications for malonate technology are supported by the company’s intellectual property portfolio and ongoing development work with formulation partners.

The company’s key patent classes include:

  • Monofunctional monomer process technology – Covers commercially viable, high yield, and low-cost synthetic and process routes to monomers with a single vinyl group.
  • Monofunctional monomer composition of matter – Covers novel monomers providing unique polymer properties, including high Tg.
  • Multifunctional monomer and oligomer composition of matter – Covers novel monomers and oligomers that allow for novel crosslinking in a broad range of chemistries.
  • Proof of concept application and formulation – Covers novel polymerizable compositions, polymers and composites formed from Sirrus monomers.
