Product superiority
1. Efficient chain transfer and precise molecular weight control
The thiol (-SH) group has high activity and can quickly terminate the growth of free radicals, precisely controlling the molecular weight of polymers and narrowing the molecular weight distribution.
Reduces high molecular branching degree, enhances the tensile strength, impact resistance and processing fluidity of the material.
2. Multifunctionality and compatibility
Suitable for various monomer systems, including styrene, butadiene, acrylate, vinyl ether, etc.
3. Excellent solubility and compatibility
The branched structure makes it soluble in styrene, butadiene and various organic solvents, has strong compatibility with the polymer system, no residual defects and does not affect the product color.
