JVP aims to design and provide resins that meet customer needs by combining resin production technology that covers a wide range of degree of polymerization as well as a wide degree of hydrolysis with functional monomer copolymerization denaturation technology.
JMR
JMR is the general term for resins with a degree of polymerization and a degree of hydrolysis ranges that differ from that of general POVAL. They and are largely classified into an ultra low degree of polymerization resins and a low degree of hydrolysis resins.
An ultra low degree of polymerization is a degree of polymerization from 100 to 400 (the degree of polymerization of general POVAL is 400 to 4000).
A low degree of hydrolysis is a degree of hydrolysis from 0 to 80 mol% (the degree of hydrolysis of general POVAL is 80 mol% or higher). JMR has many interesting properties that differ from those of general POVAL.
Denatured POVAL
- D Polymer
- A Series
- Other denatured POVAL
Denatured POVAL is the general name for POVAL that has functional groups other than hydroxyl and acetate groups of general POVAL. JVP has a commercialized D Polymer, which has carbonyl groups, and an A Series, which has carboxyl groups. Many other kinds of denatured POVAL are also available upon request.
Sodium-free POVAL
Sodium-free POVAL contains a negligible amount of heavy metals. The principal metallic constituent, sodium (Na), is kept under 1 ppm.
