Polyurethanes. About 3% of the U.S. polyurethanes market in 1988 was derived from the condensation product of polyisocyanates with low molecular weight polyadipates having hydroxyl end groups (195). In 1986 this amounted to 29,000 t, or 4% of total adipic acid consumption. The percentage was similar in Western Europe. About 90% of these adipic acid containing polyurethanes are used in flexible or semirigid foams and elastomers, with the remainder used in adhesives, coatings, and spandex fibers. 

Tartaric acid-glycerol polyesters were reported in 1847 by Berzelius [13] and those of ethylene glycol and succinic acid were reported by Lorenzo in 1863 [14]. Carothers and Van Natta [15] extended much of the earlier work and helped clarify the understanding of the polyesterification reaction in light of the knowledge of polymer chemistry at their time. Polyethylene terephthalate [16, 17] and the polyadipates [18] (for polyurethane resins) were the first major commercial application of polyesters.

The loss in properties of polyethers at 70°C (when in water) is evident with the life expectancy of 12 months. At temperatures above 50°C, the hydrolysis of polyadipate polyurethanes is such that their useful life is limited unless stabilization is used.

The polyadipates of tetrachloro bisphenol-A depicted below, containing small amounts of HPPO, are similarly used [154] as prepolymers to give, upon UV irradiation, macroradicals able to initiate the polymerization of styrene and produce block copolymers. 

It was found meanwhile that nearly every slim unbranched polymer chain, such as poly(trimethylene oxide) [224], poly(l,3-dioxolane) [225], poly(tetramethylene oxide) [226], polyethylene imine) [227], poly(3-hydroxy propionate), poly (4-hydroxybutyrate) and poly(6-hydroxyhexanoate) [228,229], poly(butylene succinate) [229], polyadipates [230], nylon-6 [231], and even oligomers of polyethylene [232], form a-CD ICs with channel structures. In all of these cases, inclusion is a heterogeneous process, since the guest polymer and its CD complex are almost insoluble in water. Therefore, extensive sonication had to be applied to accelerate the diffusion process. The polymer was also dissolved in an organic solvent, e.g., nylon-6 in formic acid, and this solution was added to the solution of a-CD [231], Alternatively, a monomer, such as 11-aminoundecanoic acid, was included in a-CD and polymerized to nylon-11 by solid state polycondensation within the channels of the IC. Thus, the IC of nylon-11 was formed under conservation of the crystal packing [233-235],...

Both monomeric and polymeric plasticizers are suitable for plasticization. Practically all monomeric plasticizers for PVC can be used. Suitable polymeric plasticizers include polyadipates, chlorinated paraffins, carbamide resins, and epoxides. Vinyl chloride copolymers are compatible with most conventional pigments and extenders. Despite their high intrinsic stability, paints based on vinyl chloride copolymers have to be stabilized against dehydrochlorination in the presence of heat and/or UV radiation for some applications. Epoxy compounds are often sufficient for thermal stabilization. 

Heteropolymers other than polyethers have been used to produce polymer electrolytes examples include esters such as polysuccinates [80], polyadipates [81] and polyimines either in the linear form [82] or cross-linked [83].

Polyester polyadipates have improved oil and chemical resistance, but slightly lower hydrolytic stability than polycaprolactones which are used for seals, gaskets, and beltings. 

Figure 13.11 illustrates the change in torsional stiffness that can occur as the temperature drops and compares polyurethane with other rubbers. There is only a small increase in the torsional stiffness as the temperature is decreased from -2(fC to about — 25" C, but then the increase in stiffness occurs very rapidly. The second-order transition point is between — 30 and —40°C and it is dependent upon the regularity of the molecular structure. Lower transition temperatures can be obtained by the use of mixed glycol polyadipates in place of the common polyethylene glycol adipate. For example, it is common commercial practice to use a blend of polyethylene...
