Linear low density poly

Methoxy propanol and water PDMS and linear low density poly (ethylene), LLDPE PDMS gave better results than LLDPE [74]... 

The phase diagram (see Figure 1) shows that there are two solution processes a low-temperature process (below 100 °C) for the production of amorphous copolymers like ethylene/propylene elastomers (EPR or EPM) [2], and a high-tempera-ture process (far beyond 100 °C) for the production of semicrystalline homo- and copolymers like high-density polyethylenes (PE-HD), linear low-density poly-ethylenes (PE-LLD) and ethylene waxes [1, 3]. Polypropylenes (PP) cannot be made in high-temperature solution processes, except for propylene waxes.

The environmental fate of linear low density poly(ethylene) films designed for mulching purposes and loaded with different pro-degradant additives has been studied (12). 

Masterbatches for PE have been described that contain a clarifying agent, a high clarity antiblock and an amide slip additive (6). These masterbatches can be used for the production of articles from both low density poly(ethylene) and linear low density poly(ethylene) by either a cast, blown or molding process. The articles show an increased gloss, a reduced haze, a reduced coefficient of friction, as well a reduced blocking force. The slip agent is erucamide. 

Fluoroelastomers are useful as processing aids. The fluoropoly-mers are normally in the fluid state at room temperature (2). The effect of the addition of an elastomer to linear low density poly(eth-ylene) (LLDPE) is shown in Figure 11.1. 

Agricultural films which are largely used in greenhouse culture or tunnel culture chiefly include soft ethylene resin films which are about 20-250 ju thick and which comprise, as a base resin, poly(vinyl chloride), branched low density poly(ethylene) (LDPE), ethylene vinyl acetate (EVA) copolymers, linear low density poly(ethylene) (LLDPE), etc. 

Antiblocking agents for film resins are summarized in Table 14.1. They find application for linear low density poly(ethylene), poly-(propylene), poly(vinyl chloride), and poly(ethylene terephthalate) in amounts of 1000-4000 ppm. These antiblocking additives are also used for a heat-sealable outer skin of a multilayer film (3). 

Linear low density poly(ethylene)-based nanocomposites exhibit a faster photo oxidation in comparison to the unfilled matrix. The acceleration is not due to a faster rate of the photo oxidation but due to the reduction of the induction time of the oxidation reaction. It is suspected that the presence of trace amoimts of metal ions in the organoclays promotes a catalytic photo oxidation. Thus, metal deactivators have been introduced into the formulations. Combinations of metal deactivators with UV absorbers show synergistic effects (12). 

PP functionalized with glycidyl methacrylate can be used for the compatibilization of poly(propylene) and poly(butylene terephthalate) blends (47). Similar studies have been done for the grafting of glycidyl methacrylate onto linear low density poly(ethylene) (48).

Although metallocene types of structures have been known for several decades [18,19], their potential as commercial catalysts remained unrealized until 1980, when Kaminsky and coworkers [20,21] discovered that methylalumoxane improved their catalytic activity dramatically. Since that discovery, massive and intense research programs have been undertaken to bring metallocene products to coimnercial fruition. Reviews of the development of metallocene catalysts can be found in papers by Horton [22] and Kaminsky [23]. The reason for this enormous interest lies in the ability of metallocene catalysts to provide well-dehned polymer products, opening the way to the molecular engineering of resins with properties tailored to the precise needs of the end user. Particular effort has been expended to replace conventional (Ziegler-Natta-type) linear low density poly-...
