“…In a batch mixer at 270°C and 60 rpm, the compatibilized PC/SAN/SAN‐MAH blend exhibited no significant dispersed phase coalescence after reducing shear rate to 5 rpm, while for the PC/SAN (70/30) blends, evident particle size growth could be observed if the shear rate decreased. Gordon Becker et al 20 modified SAN with 2‐amino alcohol or 2‐amino phenol in the presence of the catalyst (dibutyltin oxide) to introduce heterocyclic structures (ethyl hydroxymethyl oxazoline and benzoxazole, respectively). The modified SAN showed single glass transition temperature with PC in blends, which implied that the heterocyclic structures onto side groups of SAN greatly improved its compatibility with PC.…”

For the purpose of promoting mechanical properties of bisphenol-A polycarbonate (PC) reinforced by rigid organic styrene-acrylonitrile copolymer (SAN) particles, styrene/acrylonitrile/glycidyl methacrylate terpolymer (SAG) was synthesized and applied as compatibilizer for PC/SAN blends. It is found that the phase morphology of PC/SAN/SAG blends is closely related with their mechanical properties. Large continuously distributed SAN phase or spherical dispersed SAN particles with average diameter over 2 μm tend to trigger premature tensile failure of blends due to stress concentration. The incorporation of SAG can simultaneously reinforce and toughen PC/SAN blends by controlling the size and distribution of the dispersed SAN particles. For the blends with fixed PC/SAN ratio, the elongation at break and fracture energy are markedly improved when SAN domain size is reduced by adding appropriate amount of SAG. Typically, for blends with a PC/SAN ratio of 75/25, adding 3 wt% SAG will cause the average diameter of SAN particles to reduce from 2.35 ± 1.20 to 0.74 ± 0.25 μm, meanwhile up to 95% increment in elongation at break and 115% increment in fracture energy is achieved.

Blends of poly(butadiene-g-poly(styrene-co-acrylonitrile) (ABS) with polycarbonate (PC) are some of the most successful multiphase materials, with applications in the automotive and electronics industries. The mechanical properties of the complete incompatible blends are mainly determined by the interaction between the poly(styrene-co-acrylonitrile) (S/AN) component of the ABS and the PC as well as through the dispersion of the elastomeric component poly(butadiene) in the thermoplastic S/AN-matrix. The aim of our work is to optimize the modification process by the use of new substituted amino alcohols and amino phenols, as well as the use of a more efficient catalyst. Both reactive and non reactive compatibilization of polymer blends should be performed with the new ABS-modifications.

The physicochemical properties of polymers are mainly dependent on the nature of polymer backbone and/or pendant groups linked to the main chain. Therefore, synthetic modification of these functional groups via post functionalization is an important approach for obtaining novel polymeric systems with improved properties and targeted applications. In this context, the synthetic modifications of nitrile group in polymers into various useful functionalities have received considerable attention and several interesting applications of the resulting polymers have been identified. The majority of the studies are based on Polyacrylonitrile (PAN), and some isolated examples of nitrile functionalization in copolymers such as Poly (Styrene-co-Acrylonitrile) (SAN), Poly (Acrylonitrile-co-Butadiene-co-Styrene (ABS) and Nitrile Rubber (NBR) are available. These synthetic modifications are mainly accomplished by the reactions such as Nucleophilic addition, cycloaddition, reduction, and hydrolysis using various reagents. These studies describing the post-polymerization modifications of nitrile group in polymers reported during the last three decades are covered in this review.
