Which factors determine the cold temperature properties of Arkema’s functional polyolefins?

The flexibility and the impact strength at low temperature increase with higher amounts of comonomer (methyl, ethyl, or butyl acrylate; vinyl acetate) content.
The glass transition temperature (Tg) of the specific acrylate present in the Lotader® resin or Lotryl® resin also influences the low temperature properties. Butyl acrylate has a lower Tg than methyl acrylate or ethyl acrylate and therefore has better cold temperature properties:

Tg (G’’)
Methyl Acrylate: -30°C
Ethyl Acrylate: -35°C
Butyl Acrylate: -45°C
