High performance polymers are manufactured by numerous industries, and have to meet the highest requirements. The production of such products are run under high temperature and pressure conditions. Because of related process conditions the control of such processes have to follow very high safety demands.

But the safety issue is only one critical point. It is necessary to define process control and monitoring to achieve the expected properties and quality of the final product. For such applications, sonic velocity sensors are the first choice:

Determination of monomer concentration

• concentration of monomer in the solvent
• control of monomer or starter dosage
  
  

Polymerization monitoring

• real time monitoring of polymerization reaction
• detection of process disturbances for example delayed reaction start or interruption in the monomer dosage
• continuous monitoring of the reaction turn over
• precise end point determination
  
  

Concentration of polymers

• determine the concentration of monomer traces in the polymer
• direct polymer concentration measurement (concentration of lattices)
