Nanostrength®: self-assembling block copolymers

Product overview

Nanostrength® is a new family of self-assembling block copolymers that organize on the nanometer scale. When blended into a polymer matrix compatible with one of the blocks, Nanostrength® imparts unique combinations of properties to the end material such as impact strength, high rigidity, and transparency. Nanostrength® diblock copolymers allow for the modification a material’s surface properties including changes in hydrophillicity, hydrophobicity and adhesion.

Achieving this block structure is possible through Controlled Radical Polymerization (CRP), more precisely Nitroxide-Mediated Polymerization (NMP), based on Arkema‘s proprietary alcoxyamine: BlocBuilder®.


Generally, Nanostrength® block copolymers are triblock polymers consisting of polymethylmethacrylate-b-polybutylacrylate-b-polymethylmethacrylate (our MAM family) or polystyrene-b-polybutylacrylate-b-polystyrene (our SAS family).


Diblock polymers based on such monomers are also available. The different blocks (polymethylmethyacrylate or polystyrene) can be functionalized with other co-monomers of different polarity, hydrophilicity, reactivity and adhesion in order to tailor the polymer to specific needs.


 

Properties

 



  • Nanostrength is available in regular and functionalized versions to ensure compatibility with numerous polymer matrices and achieve the desired functionalization or balance of properties.

  • Nanostrength can be incorporated into the desired end-product without raising the glass transition temperature (Tg) of the existing matrix.

  • Incorporating Nanostrength® into epoxy, (meth)acrylic or PPE systems increases the material’s resistance to crack propagation.

  • Nanostrength is available in pellets, powder or microgranules to enable easy incorporation into current materials.
