The company uses two types of PVC: PVC1000 and PVC700. How can the degree of polymerization of PVC be determined? Is there a simple and practical method? Thank you to all fellow sailors! !

Just look up the **standard – it’s GB/T 3401, ‘Determination of viscosity of dilute solutions of polyvinyl chloride resin’ (GB/T 3401-1997, eqv ISO 1628-2:1988).

Measure the viscosity number, and then convert it to the degree of polymerization

The simplest and most commonly used method is the Ubbelohde viscometer method. :lol
