Description
Latent catalyst for ROMP activated by dry hydrogen chloride.
- excellent latency and shelf life – solutions of PolCat (20 – 200 mol ppm) in monomers (DCPD, norbornene and their derivatives) can be stored at room temperature for 3 - 6 months
- high activity after activation – short working time , 1 – 5 s
- usually used in two formulations system – PolCat in monomer is mixed with dry HCl in monomer in the ratio of 1:1 – 10:1, v/v
