## Abstract Near infrared (NIR) reflectance spectra recorded from poly(ethylene terephthalate) (PET) chips contain a sufficient amount of information to estimate the number of carboxylic end groups and the relative viscosity. To obtain reliable results, careful attention has to be paid to the calib
## Abstract Near infrared (NIR) transmission spectra recorded from poly(ethylene trerephthalate) (PET) melt contain a sufficient amount of information to estimate the number of carboxylic end groups and the relative viscosity. In‐line monitoring of these quality parameters is feasible.
Poly(ethylene terephthalate) and polypropylene (PET/PP) were compounded and pelletized with a single-screw extruder. Standard ASTM tensile test specimens were made by injection moulding. The blends are stronger and sti †er than the plain PP specimens. The addition of a compatibilizer, EPOLENE E-43,
