Despite their advantages, PPF and other biodegradable polymers (e.g. oligo polyethylene glycol-fumarate), generally lack the mechanical properties required for regeneration of hard and dense cortical bone, and their utility is limited to soft tissue defects and non-load bearing bone defects.

The most effective lubricants are the hydrophobic stearates, such as magnesium stearate, calcium stearate, and stearic acid. Magnesium stearate is the most widely used lubricant [117,118]. Lubricants proposed as being less hydrophobic such as hydrogenated vegetable oils, polyethylene glycols, and sodium stearyl fumarate are less effective in this application [118]. [Pg.366]

A combination of 4% polyethylene glycol (PEG) 6000 and 0.1% sodium stearyl fumarate proved to be a good lubricant for ascorbic acid tablets made by direct compression on a small scale. Sodium chloride, sodium acetate, and D,L-leucine (water-soluble lubricants) also have been suggested for effervescent tablets. ... [Pg.1459]

Cross-linked polyesters have been investigated mainly for applications in drug release systems. At least two types can be distinguished. In the first type, which can be described as polyester hydrogels, a diacid is reacted with a diol (or polyol), with unsaturation in either or both monomers [206-207]. Fumaric acid and polyethylene glycol (PEG) yield typically the following structure ... [Pg.113]

In addition to MA, phthalic anhydride, and ethylene glycol, other common intermediates used for the production of unsaturated polyesters are fumaric acid, isophthalic acid, adipic acid, propylene glycol, diethylene glycol, and dipropylene glycol. Table 12.1 provides a summary of both common and specialty building blocks used in polyesters and contributions made by these intermediates to the properties of the products. Recycled polyethylene terephthalate beverage bottles may one day become an important raw material for unsaturated polyester resin production, providing an alternative for a substantial part of the petroleum-based intermediates.

MMA), when copol3rmerised with ethylene glycol dimethacrylate (EDMA) or polyethylene fumarate (PEF), but not with styrene, enters stage II sharply at the gel point. A plausible model proposed by Gordon and Roe leads to a parameter-free rate equation fig. M-), which fits extensive measurements on MMA/EDMA and MMA/PEF very well over the range 0 < < 6 Fig. M- contains... [Pg.12]
