Ethene-vinyl acetate copolymers

Impact modification. Post-reactor impact modification commonly will be done by the addition of EPR, ethylene-propylene-diene rubber (EPDM) or special resins like ethene-vinyl acetate copolymers (EVA), but also with the new generation of linear low density polyethylene (LLDPE) produced by metallocene catalysts.

Ethylene vinyl acetate (EVA) is a copolymer from ethene and vinyl acetate. Several variants of this type are known and described in this chapter. [Pg.187]

The practically most important copolymer is made from ethene and propene. Titanium- and vanadium-based catalysts have been used to synthesize copolymers that have a prevailingly random, block, or alternating structure. Only with Ziegler or single site catalyst, longer-chain a-olefins can be used as comonomer (e.g., propene, 1-butene, 1-hexene, 1-octene). In contrast to this, by radical high-pressure polymerization it is also possible to incorporate functional monomers (e.g., carbon monoxide, vinyl acetate). The polymerization could be carried out in solution, slurry, or gas phase. It is generally accepted [173] that the best way to compare monomer reactivities in a particular polymerization reaction is by comparison of their reactivity ratios in copolymerization reactions. [Pg.32]

Whereas homopolymerizations of maleic or fumaric add derivatives have not yet found technical interest, copolymers derived from MAH and various vinyl monomers are commercialized by several chemical companies. Such commerdal copolymers may be based on styrene (Scriptset or SMA), ethene (EMA, Malethamer, VINAC), isobutene (ISOBAM), butadiene (Maldene), vinyl alkyl ethers (Gantrez AN or Viscofres), and vinyl acetate (Lyfron, Benex, Amoco DriUing Aid 420,421, or Baroid X tend). [Pg.307]

Ethene is the principal co-monomer ( 60-80%) in poly(elhene/vinyl acetate) (EVA) copolymers (Zutty et al., 1967). The vinyl acetate (VAC) component reduces crystallinity and increases flexibility (Tg below O C). It also inaeases adhesion and solubility (Appendix 3). The presence of VAC in the copolymer reduces the cross-linking tendency under ultraviolet ageing until at 25% VAC this reaction is negligible (Feller and Curran, 1970). [Pg.143]

Vinyl Resins n (1934) According to common chemical nomenclature, all resins and polymers made from monomers containing the vinyl group, H2C=CHX. In the chemical literature, polystyrene, polyolefins, polymethyl methacrylate and many other styrenic, ethenic, and acrylic copolymers are classified as vinyls (Mishra, M. K. M., and Yagci, Y., Handbook of Vinyl Polymerization Marcel Dekker, New York, 1998). In the plastics literature, the above materials are given their own classifications and the term vinyl is restricted to compounds in which X, above, is not H, a hydrocarbon radical, nor an acrylic-type ester. In daily use, the term vinyl plastics refers primarily to Polyvinyl Chloride and its copolymers, and secondarily to the following Polyvinyl Acetal, Polyvinyl Acetate, Polyvinyl Butyral, Polyvinyl Dichloride, Polyvinyl Formal, Polyvinylidene Chloride, Polyisobutylvinyl Ether, and Poly(l-Vinylpyrrolidone). [Pg.796]

Ethene, the most important petrochemical feedstock today, reached a world capacity of about 80 million tons per year in 1995. Almost half is polymerized to give polyethylene. It plays only a secondary role for emulsion polymerization in vinyl acetate-ethene copolymers and in polyethylene waxes. It is important, however, in this connection as a feedstock for the production of vinyl chloride, styrene and vinyl acetate. [Pg.8]
