Description

BlocBuilder® Technology refers to Arkema’s nitroxide-based controlled radical polymerization technology, useful in developing polymers with novel tailored performance properties.
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.

Benefits

Controlled free radical polymerizations :

• 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

End Product :

• Controlled nanostructure
• Customized polymer properties including improved toughness, compatibility, surface properties, adhesion, rheology, and aesthetics
