Polyethylene adipate , thermal

A further approach is used by Bayer with their polyesteramide BAK resins. A film grade, with mechanical and thermal properties similar to those of polyethylene is marketed as BAK 1095. Based on caprolactam, adipic acid and butane diol it may be considered as a nylon 6-co-polyester. An injection moulding grade, BAK 2195, with a higher melting point and faster crystallisation is referred to as a nylon 66-co-polyester and thus presumably based on hexamethylene diamine, adipic acid and butane diol. 

Like PU TPE, blends of thermoplastic polyurethanes and polyamide-12 (PA-12) have been studied by Polosmak and co-workers [61]. They have mixed two types of thermoplastic polyurethane (TPU) based on oligoether (polytetramethylene oxide, molecular weight, 1000) and oligoester (polyethylene butylene glycol adipate, molecular weight, 2000) and PA 12 were characterised by IR spectra and thermal analysis. IR spectra of TPU, PA-12 and their blends show that in amide one (Al) carbonyl absorbancy is seen to split [55] into two main bands with maxima at 1705 and 1730 cm 1. At 1730 cm 1,... 

Formation of a polymer alloy is a common way to improve the property of PLLA. Many kinds of polymers such as polyethylene [70], polypropylene (PP), polystyrene (PS) [71], poly (methyl methacrylate) [72], bisphnol-A type polycarbonate, poly(E-caprolactone), poly(3-hydroxybuty-rate), poly (butylene succinate) (PBS) [73], poly(butylene succinate/adipate) (PBSA), acrylonitrile-butadiene-styrene have been used for preparing PLLA alloys, and some of which have been commercialized. However, there has been no discussion of the thermal degradation behavior of the PLLA component.
