BlocBuilder® Technology refers to Arkema’s nitroxide-based controlled radical polymerization technology, useful in developing polymers with novel tailored performance properties.
Visit our Nanotechnology site, which includes information on our complete BlocBuilder® product lines, including our newest - BlocBuilder® RC-50 reactivity controller, ideal for use in the composites industry.
For example, the technology can be used to produce acrylic block copolymers for a wide range of applications.
BlocBuilder® is the tradename for a remarkable new alkoxyamine compound that combines an initiator and polymerization control agent in one molecule. FlexiBlocTM is the tradename for a developmental product line of reactive macroinitiators, for use by polymer producers or compounders.
- Reduced polydispersity (tighter molecular weight distribution)
- Controlled copolymer sequencing, allowing manufacture of block, gradient, and star copolymers
- Compatibility with existing reactor equipment to minimize capital investment
- No need to remove residual metallic or sulphuric compounds which can be problematic with other approaches
