Lactic acid is currently produced by fermentation of carbohydrates and is rme of the high potential and versatile biomass-derived platform chemicals, leading to various useful polymer products. PLA is produced by ROP of lactide (derived from lactic acid) and exhibits mechanical properties similar to poly(ethylene terephthal-ate) and polypropylene. Representative examples discussed herein included the synthesis of highly stereo-controlled PLAs, such as isotactic, heterotactic, and syndiotactic PLA materials, rendered by different catalyst/initiator systems. [Pg.217]

Abstract Succimc add is an important platform chemical derived from petrochemical or bio-based feedstocks and can be transformed into a wide range of chemicals and polymers. Increasing demand for biodegradable poly(butylene succinate) (PBS) will open up a new market for succinic acid. In this chapter, the synthesis of succinic acid is briefly reviewed. We focus on the polymerization, crystalline structure, thermal and mechanical properties, and biodegradability of PBS and its copolymers. PBS shows balanced mechanical properties similar to those of polyethylene and excellent performance during thermal processing. In addition, PBS and its copolymers can biodegrade in various enviromnents, such as soil burial, river, sea, activated... [Pg.347]

The main resist polymer platforms used in this form of chemical amplification comprise poly(hydroxy styrene), acrylate, alicyclic, and hybrid acrylate-alicyclic systems. Because of the great versatility of polyhydroxystyrene (PHOST) in... [Pg.343]

The design of biologically active surfaces offers a new dimension to the development of advanced materials for biomedical and microfluidic applications. Our approach to creating these surfaces is via the fabrication of vapor-based reactive polymer coatings, which provide sophisticated functional groups for the immobilization of biological ligands. Chemical vapor deposition (CVD) polymerization has been used to prepare a wide spectrum of hinctionalized poly(p-xylylenes). The applicability of a few of these reactive surfaces as stable platforms for biomimetic modifications is discussed in this review. [Pg.283]
