Abstract:

Most polymeric materials are based on non-renewable fossil resources, respectively petrochemicals. As regenerable resources carbohydrates have attracted great attention in the last decade for production of polymeric materials. The biodegradable polymers are indispensable in the modern society and their importance is continuously growing. In this paper we report the thermal properties of a new class of biodegradable copolymers derived from monosaccharides. The glycomonomers 3-O-acryloyl-1,2:5,6-di-O-isopropylidene-α-D-glucofuranose, and 1-O-acryloyl-2,3:5,6-di-O-isopropylidene-α-D-mannofuranose, were co-polymerized with 2-hydroxypropyl methacrylate, using benzoyl and lauroyl peroxide as initiators. The copolymerization process between glycomonomers and 2-hydroxypropyl methacrylate was studied using differential scanning calorimetry analysis (DSC). The storage and loss modulus were evaluated using DMA technigue (dynamic mechanical analysis), while the thermal stability of the obtained products was studied via thermogravimetry (TG).


Keywords: carbohydrate, biodegradable polymer, thermal analysis, DSC, DMA, TG.
