High-performance TPE based on a polyamide (aka nylon) hard block along with a soft segment. PAEs are also known as polyether block amides or as copolyester amides or thermoplastic elastomer-amides. They are used mainly in areas where other TPE cannot compete/ perform, especially at lower temperatures. 

Poly(ether-b-amide). In these particular thermoplastic elastomers the hard blocks consist of aliphatic polyamides, whereas the soft segments are formed of aliphatic polyethers.

The PIB macroinitiators can also initiate living anionic polymerization of a wide variety of functional monomers, such as vinyl pyridine, N,N-dimethylacryl-amide, and a variety of protected monomers, such as silylated 2-hydroxyethyl methacrylate. Polymerization studies with these monomers are in progress. The resulting products are potential new thermoplastic elastomers, dispersing agents, blending compounds, emulsifiers, non-ionic surfactants, biomaterials etc. 

Thermoplastic polyamides are a relatively new class of block-copolymer thermoplastic elastomers. They have amide linkages between the hard and soft segments. This class of thermoplastic elastomers has the highest performance and is the most expensive of the TPEs.

The rubbery materials, which are processed as thermoplastics, are usually treated as thermoplastics and identified in the same way. However, they are sometimes referred as TPE (which stands for thermoplastic elastomer) and then, these letters are followed by another letter which identifies the type of TPE. For example, TPE-A means that it is amide based, TPE-U means that is urethane based and, TPE-0 means that it is olefin based. 

Polyaddition of organosilicon dihydrides, mainly dihydro(poly)siloxanes to dialkenyl-substituted organic compounds also known as hydrosilylation copolymerization, leads to polycarbosiloxanes with functionalized organic segments (359). Platinum-catalyzed polymerization hydrosilylation of a,allyl-substituted bisphenols, imides, or amides leads to the synthesis of block copolymers that are useful thermoplastic elastomers (Scheme 40). 

Thermoplastic elastomers (TPEs), which combine the characteristics of both thermoplastics and elastomers, can be classified into two major groups. The first is made up of block copolymers formed by polymerizing a thermoplastic monomer with an elastomer comonomer, as in the case of styrene block copolymers such as styrene-ethylene-butadiene-styrene (SEBS). Engineering TPEs such as thermoplastic urethanes (TPUs), copolyesters (COPEs) and polyether block amides (PEBAs) can be included in this first group. Other types of copolymer are from the polyolefin family, consisting of the polyolefin...

This growing family of thermoplastic elastomers, known generically as polyether block amides (PEBA), is comprised of rigid polyamide blocks and flexible polyether blocks. 

By itself, a summary of the history of polyether block amide thermoplastic elastomers would indeed be a relatively short story as these types of resins are still quite young in terms of commercial development. However, the rapid market acceptance and future growth potential for this new class of engineering resins makes the documentation of their development a worthwhile endeavor at this time. To complete the story on polyether block amides, a review of the chemistry, properties and major end-uses of these resins is also included. 

By this time it was evident that a commercial market for PEBA did exist. Several applications targeted during the early development of the product appeared to be feasible and a need for commercial quantities of the resin was imminent. In 1981 a commercial production line was brought On stream in Europe, and a unique new family of polyether block amide thermoplastic elastomers under the tradename of PEBAX polyether block amide was formally introduced at Interplas in Birmingham, England. 

Following the U.S. introduction of PEBAX in 1981, a market for the product rapidly developed. Based On the apparent future demand for this new family of resins, a commercial production facility for polyether block amide thermoplastic elastomers was brought on Stream in the U.S. 

Due to the diversity of polyether block amide thermoplastic elastomers that can be produced, a discussion of their specific properties would be a rather lengthy exercise. Even to list the properties of all the possible combinations of a particular set of polyamide and polyether segments could prove cumbersome as the amount of either segment in the copolymer may vary between ten and ninety percent. Therefore, a discussion of the properties of PEBA can be best accomplished by citing overall performance characteristics and ranges of values. Several properties worth noting include ... 

Polyether block amide thermoplastic elastomers are processed on conventional thermoplastic processing equipment. Typical processing temperatures are in the range of 195°C to 260°C. Being a condensation polymer, the resin should contain no more than 0.1% moisture when processed to avoid hydrolysis. Most commercial grades of PEBA can be processed... 

Although a relatively new family of engineering thermoplastic elastomers, polyether block amides have found a place in the growing family of engineering resins. The versatility of the polyether block amide chemistry and the wide variety of achievable performance characteristics has resulted in very rapid growth of this class of resins. ATOCHEM expects this growth to continue for many years to come as further research and development unveils new formulations, stabilization systems, polymerization processes and applications.
