The Material of the Example. Poly(ether ester) (PEE) materials are thermoplastic elastomers. Fibers made from this class of multiblock copolymers are commercially available as Sympatex . Axle sleeves for automotive applications or gaskets are traded as Arnitel or Hytrel . Polyether blocks form the soft phase (matrix). The polyester forms the hard domains which provide physical cross-linking of the chains. This nanostructure is the reason for the rubbery nature of the material. [Pg.172]

In view of the functionality thus created, it is interesting to consider possible applications for the epoxldlzed oils mentioned as epoxy monomers per se. Indeed, some epoxldlzed oils are commonly used as reactive diluents for other epoxy prepolymers in order to reduce cost or Improve processability (10,11) examples claimed in reference 11 Include epoxldlzed linseed, butylated linseed, soybean, and tall oils. However, although some fundfimental studies of the effects of monofunctional reactive diluents on the viscoelastic and other properties of epoxy resins have been published (see, for example, reference 12), little or no analogous Information on the effects of multifunctional reactive diluents appears to exist. At the same time, some reactive additives such as polyols (13), poly(ether esters) (14) and carboxy-terminated elastomers (15) have been used to provide an elastomeric toughening phase for epoxies.

Condensation polymerization and stepwise addition polymerization are, for example, applied for the preparation of block polyesters. The synthesis concepts are different from those of chain polymerization in that at least one monomer is an oligomer with one or two functional end groups, for example polytetrahy-drofurane with a molecular weight of several hundred and OH-end groups (see Example 3.23). If this oligomer partially replaces butandiol in the condensation polymerization with terephthalic acid (compare Examples 4.1 and 4.2), a poly(ether ester) is obtained with hard polyester segments and soft polyether segments and with the properties of a thermoplastic elastomer.

The same approach (assuming if = 0 for the soft component and/or phase) applied to thermoplastic elastomers of poly(ether ester) (PEE) type fails also to explain the large discrepancy (up to 100 MPa when the measured H values are in the range of 20-40 MPa) between the experimental values and those calculated according to Eq. (13.1) [11,12]. For this reason, one has to look for other factors, which may be responsible for such a discrepancy. Before discussing them, let us recall briefly some of the characteristic features of the structure and morphology of thermoplastic elastomers of PEE-type, which illustrate in the best way the concept under discussion.

Poly(ether-ester) (PEE) copolymers obtained by modification of poly(ethyl-ene terephthalate) with up to 20 wt% of poly(ethylene ether) glycol was first described by Coleman [8]. Subsequently, the DuPont Co. developed poly(ether-ester) elastomers, which were commercially introduced in 1972 under the trade name Hytrel [4,9]. The polyester thermoplastic elastomers are nowadays produced by several companies. Apart from DuPont, these are DSM, The Netherlands (Arnitel ), General Electric, USA (homed ), Hoechst Celanese, USA (Retiflex ), Toyobo, Japan (Pelprene ), Elana, Poland (Elitel ) [2,10]. The synthesis, chemical structure, physical properties, and some new applications of polyester TPE are discussed in this chapter (about the development of TPE, see also Chapter 1, while details on some commercial TPE products can be found in Chapter 17).
