Novel monomers, combining synthetic and natural compounds,
methacrylated glucose (MGlu) and acrylated glucose (AGlu), and their
polymers and hybrid copolymers with methyl methacrylate (MMA) or
MMA/N-vinylpyrrolidone (MMA/NVP, 1:1), at 10, 20 or 30wt.% MGlu or
AGlu, were synthesized. These polymeric materials were characterized
over the broad temperature range by DMA and TGA, and also in the
biodegradation tests. Constrained dynamics effect and more pronounced
dynamic heterogeneity over the broad temperature range, with
increasing 
values by ~15°C-30°C, were registered in all
cases in the hybrids compared to those in the initial polymers. Some
increase in the thermal stability at ~150°C-240°C was attained in
some of the hybrids. A considerable rise of modulus and essential
enhancing of biodegradability were also registered but only under
conditions of elevated polymer hygroscopicity, i.e., for MMA/NVP
copolymer.
