They concluded that the PLA at 650 Da was best suited as a carrier for BMP due to its material properties, handling characteristics and resorbability. , 1999). Bone formation was less than expected, and the investigators felt it was due to the high acidity and rapid degradation of the low molecular weight homopolymer. A polyethylene glycol (PEG) moiety was added to the PLA homopolymer, and poly-d,l-lactic acid–polyethylene glycol (PLA-PEG) block copolymers were introduced. , 1993). , 2000). The excellent chemical resistance, physical properties and biodegradability of PVA have led to the development of many commercial products based on this polymer.
The ability to obtain such a wide range of tensile strength values makes the polymer appropriate for diverse applications. The dielectric behaviour of the polymer is determined by the charge distribution and also by statistical thermal motion of its polar group. Bao and Higham (1991, 1993) have approached nucleus replacement using physically crosslinked polyvinyl alcohol (PVA). The authors reported that PVA implant has similar mechanical properties to those of the nucleus as well as similar physiological properties, maintaining about 70% water content under physiological loading conditions.
