Vn. Ignatov et al., PET PC BLENDS AND COPOLYMERS BY ONE-STEP EXTRUSION .2. INFLUENCE OF THE INITIAL POLYMER COMPOSITION AND TYPE OF CATALYST/, Polymer, 38(1), 1997, pp. 201-205
One-step extrusion proved to be an innovative technique for the produc
tion of poly(ethylene terephthalate)/bisphenol A polycarbonate (PET/PC
) compatible blends and copolymers by transesterification in the prese
nce of a small amount of catalyst which was mechanically dispersed on
the polymers before their extrusion. This method provides possibilitie
s for producing a variety of polymeric materials with different therma
l and physico-chemical properties by varying the initial polymer compo
sitions, concentrations and type of catalyst. Copyright (C) 1996 Elsev
