The use of olefin rubbers [18] as good impact modifiers for sPS when used in conjunction with S-B or S-B-S block copolymers, which may be hydrogenated in the butadiene phase, has also been described. Instead of butadiene, isoprene can be used. Examples of the olefinic polymers are polyethylene, ethylene-propylene rubbers (EPR) and polypropylene-(ethylene propylene rubber) block copolymers. Here the styrene block copolymers presumably function as... [Pg.421]

H5V was used as grafting monomer for atactic polypropylene, ethylene/propylene copolymer, ethylene/vinyl acetate copolymer, poly(methyl acrylate) and poly(methyl methacrylate) (32). In all cases, grafting was achieved in chlorobenzene with ditertiarybutyl peroxide as the initiator. Up to now, we have not succeeded in grafting 2H5P under the same conditions onto these polymers.

Danes and Porter [90], studying (polypropylene/ethylene propylene rubber) blends, found that finer dispersions were obtained when the minor phase had an equal or lower viscosity than the major phase. If the minor phase had a higher viscosity, coarser blends were obtained. [Pg.280]

Schaefer et al. (19) studied the interphase microstructure of ternary polymer composites consisting of polypropylene, ethylene-propylene-diene-terpolymer (EPDM), and different types of inorganic fillers (e.g., kaolin clay and barium sulfate). They used extraction and dynamic mechanical methods to relate the thickness of absorbed polymer coatings on filler particles to mechanical properties. The extraction of composite samples with xylene solvent for prolonged periods of time indicated that the bound polymer around filler particles increased from 3 to 12 nm thick between kaolin to barium sulfate filler types. Solid-state Nuclear Magnetic Resonance (NMR) analyses of the bound polymer layers indicated that EPDM was the main constituent adsorbed to the filler particles. Without doubt, the existence of an interphase microstructure was shown to exist and have a rather sizable thickness. They proceeded to use this interphase model to fit a modified van der Poel equation to compute the storage modulus G (T) and loss modulus G"(T) properties. [Pg.435]

Irradiation of Isotactic Polypropylene and Polypropylene/Ethylene-Propylene- (diene-monomer) Blends... [Pg.128]

The influence of electron beam irradiation on rheological properties and morphology of polypropylene and polypropylene/ethylene-propylene rubber blends was studied. Electron beam irradiation of isotactic PP causes pronounced chain scission (degradation) at dosis < 100 kGy. Melt viscosity can be controlled easily up to this dose for pure PP. For the blende however, an anomalous rheological behaviour is observed. [Pg.128]

Rubber blending of PP is used to improve its impact properties. Miscibility, however, is exception rather than rule in polymer systems and consequently processing of polymer blends is quite complicated with respect to control of morphology. An induced morphology may be preserved using radiation techniques to crosslink the dispersed phase in polymer blends isotactic-polypropylene/ethylene- propylene (diene... [Pg.129]
