General Conclusions on Polyamide Modification

Comparing the results of the modification of PA-6 end groups with either succinic anhydride, 1,2-epoxybutane, or diketene and the diketene acetone adduct, it can be concluded that the optimal blocking agent must be small and must exhibit an intermediate reactivity toward the end groups in order to allow extensive penetration into the core of the granules before the blocking reaction starts to hinder further penetration. 

Carboxylic Acid End-group Modification of Poly(Butylene Terephthalate] with 1,2-Epoxy butane in Supercritical COj 

Poly(butylene terephthalate), PBT, is a material which is widely used in a variety of applications, one of which is for optical fiber tubing. These fiber tubes are buried in the ground, and therefore it is necessary for this application that the
