Erosion kinetics of hydrolytically degradable polymers.
Degradable polymers are beginning to play an increasing role as materials for environmental and medical applications. Understanding factors that control erosion, such as bond cleavage and the dissolution and diffusion of degradation products, will be critical to the future development of these materials. Erosion kinetics, photomicroscopy, and infrared spectroscopy were used to understand the er...
متن کاملNew synthetic approaches to prepare degradable polymers
This thesis is concerned with the synthesis of acid labile co-polymers. Two polymer systems were examined (1) polyacetals and (2) poly(ortho esters). As for poly(ortho esters), there is a need for better synthetic methods to prepare these polymers more easily without the need of stringent anhydrous conditions, with more broad structural variation, and in a more cost effective manner. Pendent fu...

متن کاملNon-degradable biocompatible polymers in medicine: past, present and future.
Polymers have a long history in medicine. Their uses to date range from traditional applications such as catheters, syringes, blood contacting extra corporeal devices to matrices for drug delivery, cell encapsulation and tissue regeneration. Polymers can be broadly classified on the basis of the reactivity of their chemical backbone (or susceptibility of the backbone to breakdown upon exposure ...
متن کاملLarge Intestine
The equine large intestine consists of the following segments (in aboral direction): the cecum, the large colon, and the small colon (Fig. 36-1). Although these segments form a continuum for the passage of digesta from the ileum to the anus, the three portions are considered to be separate structures, anatomically, functionally, and surgically. The large intestine of the horse is well developed...
