This document specifies a method for determining the percentage of matter which can be extracted from crystalline propylene plastics by boiling n-heptane under standard conditions of testing. Isotactic index is determined by conventional chemical extraction as an absolute method.
This method provides for the identification and coding of types H, B and R propylene plastics according to ISO 19069-1[ 1].
This method is suitable only for base polymers and is not applicable for mixtures.
This method starts with solid propylene plastics in the form of particles of specified fineness.
