Ethylene methyl acrylate copolymer

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]

An example of this improvement in toughness can be demonstrated by the addition of Vamac B-124, an ethylene/methyl acrylate copolymer from DuPont, to ethyl cyanoacrylate [24-26]. Three model instant adhesive formulations, a control without any polymeric additive (A), a formulation with poly(methyl methacrylate) (PMMA) (B), and a formulation with Vamac B-124 (C), are shown in Table 4. The formulation with PMMA, a thermoplastic which is added to modify viscosity, was included to determine if the addition of any polymer, not only rubbers, could improve the toughness properties of an alkyl cyanoacrylate instant adhesive. To demonstrate an improvement in toughness, the three formulations were tested for impact strength, 180° peel strength, and lapshear adhesive strength on steel specimens, before and after thermal exposure at 121°C.

Other commercially relevant monomers have also been modeled in this study, including acrylates, styrene, and vinyl chloride.55 Symmetrical a,dienes substituted with the appropriate pendant functional group are polymerized via ADMET and utilized to model ethylene-styrene, ethylene-vinyl chloride, and ethylene-methyl acrylate copolymers. Since these models have perfect microstructure repeat units, they are a useful tool to study the effects of the functionality on the physical properties of these industrially important materials. The polymers produced have molecular weights in the range of 20,000-60,000, well within the range necessary to possess similar properties to commercial high-molecular-weight material. [Pg.460]

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.

Several polymers were evaluated in the form of a surface coating on glass beads packed in columns to determine their ability to retain platelets when whole human blood passes over the surface. This ability was measured as the platelet retention index p, the fraction of platelets retained on the column. Lowest values of p were found for poly(ethylene oxide), polypropylene oxide), poly(tetramethylene oxide) (in the form of polyurethanes), and polydimethylsiloxane. Highest values (around 0.8) were found for cross-linked poly(vinyl alcohol) and the copolymers of ethylenediamine with diisocyanates. Intermediate values were found for polystyrene and its copolymers with methyl acrylate, for polyacrylate, and for poly(methyl methacrylate). The results are interpreted in terms of possible hydrophobic and hydrogen bonding interactions with plasma proteins. [Pg.41]

A typical structure of an ethylene/methyl acrylate (E/MA) copolymer is very similar to an ethylene homopolymer produced by the same a-diimine palladium catalysts, see Figure 3. The EMA copolymers are amorphous, highly branched materials with about 100 branches per 1000 carbon atoms and with glass-transition temperatures typically ranging from —50 to —70 Simultaneous RI and UV...

Ethylene—methyl acrylate (EMA) copolymers react with sodium cyclopentadienide yielding a polymer-bound Cp anion, which forms an EMA-bound metallocene when combined with CpZrCE or ZrCl4(THE)2 (Scheme 16). Both catalysts polymerize ethylene in isobutane or toluene slurries to polyethylene of relatively narrow molecular weight distribution MJ Mn = 2.3—3.0) when activated by MAO. [Pg.476]
