Home » Analytical Services » Intrinsic Viscosity Analysis by IVA Intrinsic Viscosity Analysis Overview This service provides the Intrinsic Viscosity (IV) of any polymeric material, including challenging ones such as high and ultrahigh molar mass polymers. The viscosity test is performed in Polymer Char’s Intrinsic Viscosity Analyzer (IVA), which is compatible with any organic solvent such as decalin, tetralin, tri-chlorobenzene (TCB) and ortho-dichlorobenzene (o-DCB) among many others. Dissolution and analysis temperatures can be set independently, from ambient temperature to 200ºC, so that a wide range of polymers can be analyzed, even the most crystalline ones. A study conducted by Polymer Char with different polymers in various solvents – PAN (polyacrylonitrile) in DMF (N,N-dimethylformamide), PET in phenol:o-DCB, PLA in TCB, and polyolefins in TCB and o-DCB – shows that all the intrinsic viscosity results obtained with IVA are in good agreement with the standard methods used as reference (compared to IV obtained with the traditional glass capillaries of the Ubbelohde type ISO 1628-3:2010 f.i. and ASTM D1601). Request a Quotation Intrinsic Viscosity Analysis Results The following are some results of samples analyzed by IVA: PET in phenol:oDCB (2:3, m:v) IVA method, 35ºC (dL/g) Correlation of intrinsic viscosity (IV) values obtained using the IVA method compared to IV determined using a traditional glass capillary setup for a set of PET samples. In both cases a mixture of phenol:o-DCB (2:3, m:v) was used while temperatures were 35ºC and 25ºC respectively. Ethylene-Propylene copolymers in TCB IVA method TCB @150ºC (dL/g) Correlation of intrinsic viscosity (IV) values obtained using the IVA method compared to IV determined according to standard method ISO 1628-3:2010 for a set of polypropylene samples. IVA was run in tri-chlorobenzene at 150ºC, using solutions prepared at 1 mg/mL; the ISO method was performed in decalin at 135ºC with solutions at 1-1.5 mg/mL. The linear correlation is excellent as proved by the high R2 value. Dissolution vial atmosphere Observed viscosity for a UHMWPE sample with different dissolution time, with and without nitrogen purge of the dissolution vial.
