Physico-mechanical properties of the products based on filled epoxy-oligomeric mixtures composed of Epidian-5 epoxy resin, oligoesteracrylate TGM-3 and monoperoxide derivative of Epidian-6 epoxy resin (PO) have been investigated. CaCO 3 was used as a filler and polyethylene polyamine was a curing agent. The effect of PO and CaCO 3 on the gel-fraction content and physicomechanical properties was examined. Using a scanning electron microscopy (SEM) the morphology of the samples has been studied.

The performance of polypropylene-poly(ethylene brassylate) block and graft copolymers and a polypropylenepolycaprolactone graft copolymer as compatibilizers for polypropylene-rich polypropylene/bisphenol A polycarbonate (PP/PC, 80/ 20 wt/wt) blends was elucidated. The copolymers were synthesized either by metal-catalyzed ring-opening polymerization or transesterification of a presynthesized polyester, initiated by hydroxyl-functionalized PPs, which themselves were obtained by catalytic routes or reactive extrusion, respectively. Spectroscopic fingerprints of the copolymers from liquid-state nuclear magnetic resonance (NMR) in combination with scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), dynamic mechanical thermal analysis (DMTA), and rheology analyses of the blends indicated that the compatibilizers spontaneously organize at the interface of the two immiscible polymers leading to the formation of uniform, stable, nanophase morphologies. The effect of the compatibilizers on the performance of the PP/PC blends was evaluated, and wellcompatibilized PP/PC blends showed improved melt strength and strain hardening when compared to pure PP. This was verified by the successful foam extrusion using isobutane as a blowing agent of well-compatibilized PP/PC blends to low-density PP-based foams, for which normally long-chain branched PP is required.

Abstract. New hydroxy-derived resin with primary hydroxy and epoxy groups has been synthesized on the basis of ED-20 epoxy resin and PolyTHF-2000 oligoether. The structures of the synthesized derivative and the product based on ED-20 epoxy resin and 1,4-butanediol which was synthesized by us earlier have been confirmed by IR-and NMR spectroscopy. The synthesized derivatives were investigated as polymeric components for bitumen-polymeric blends.
