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 کاملSynthesis of (Bio)degradable Polymers via Thiol-ene Click Polymerization
Towards the development of (bio)degradable polymers with medical relevance a non-radical thiolene synthesis route is investigated. In this work, step growth polymerization based on Michael addition click reactions is presented. Homotelechelic RAFT polymers were conjugated leading to polymers with molar weight distribution typical for a step growth polymerization, tailing up to 100 000 g∙mol-1 i...
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 ...
