Blends of poly(styrene-co-acrylonitrile) with polyethylene-co-propylene-co-diene have been characterised by SEC with UV and refractive index detectors, which allowed for the determination of average blend composition as a function of elution volume, and by precipitation LC, which allowed for complete separation of the blend components [112].

UNIPOL [Union Carbide Polymerization] A process for polymerizing ethylene to polyethylene, and propylene to polypropylene. It is a low-pressure, gas-phase, fluidized-bed process, in contrast to the Ziegler-Natta process, which is conducted in the liquid phase. The catalyst powder is continuously added to the bed and the granular product is continuously withdrawn. A co-monomer such as 1-butene is normally used. The polyethylene process was developed by F. J. Karol and his colleagues at Union Carbide Corporation the polypropylene process was developed jointly with the Shell Chemical Company. The development of the ethylene process started in the mid 1960s, the propylene process was first commercialized in 1983. It is currently used under license by 75 producers in 26 countries, in a total of 96 reactors with a combined capacity of over 12 million tonnes/y. It is now available through Univation, the joint licensing subsidiary of Union Carbide and Exxon Chemical. A supported metallocene catalyst is used today. [Pg.280]

The radical initiated copolymerization of C2H4 and CO in the presence of a polyolefin has been reported to result in the grafting of the C2H —CO copolymer onto the polyolefin backbone31). Polyolefins used included polyethylene, ethylene-propylene copolymer and polyisobutylene. [Pg.131]

Glycidyl methacrylate has also been grafted to polyethylene and to poly(ethylene-co-propylene) using peroxides in extruders.87 The reactive group need not be pendant. It can be part of a copolymer. Ethylene-methyl acrylate copolymers and styrene-maleic anhydride copolymers have been reacted with ammonia and with amines in extruders.88... [Pg.209]

Polyolefine blends are group of versatile materials, which properties can be tailored to specific applications already at the stage of compounding and further processing. Our previous papers on elastomer/plastomer blends were devoted to phenomenon of co crystallization in isotactic poly-propylene/ethylene-propylene-diene rubber (iPP/EPDM) [1] or surface segregation in low-density polyethylene/ethylene-propylene-diene rubber (LDPE/EPDM) [2, 3] systems. Composition and structure of the materials were related to their properties. Recently, we have described the influence... [Pg.4]

Interfacially active graft or block copolymers of the t5 pe A-B or A-C may compatibilize the immiscible polymers A and B provided that C is also miscible or capable of strong interactions with B. Poly(ethylene-co-propylene) elastomer (EPR) or poly(ethylene-co-propylene-co-diene) (EPDM) is an example of such nonreactive compatibilizer for polyethylene/polypropylene (PE/PP) blends. [Pg.696]

The photo-oxidative degradation of poly(ethylene-co-propylene-co-l,4-hexadiene) (3.133) occurs by a combination of reactions characteristic of the degradation of polyethylene and polypropylene (section 3.1) and polydienes (section 3.12). Quantum yields of different photochemical processes which occur in this terpolymer are shown in Figure 3.68. [Pg.251]
