✦ Synopsis
Hybrid organic-inorganic materials were prepared by using two different zinc salts and poly(acrylic acid) (PAA). The characterization of the resulting compounds show that polymerlike materials with a decomposition temperature above 673ЊC can be produced and that the specific zinc salt and synthesis route influence the final properties of these materials.

## Abstract Potassium persulfate (K~2~S~2~O~8~) was used to initiate the polymerization of acrylic acid (AA) monomer in a chitosan (CS) solution. Both a poly(acrylic acid) (PAA) homopolymer and a CS‐__co__‐PAA copolymer were produced. When the amount of AA was increased from 5 to 40 g with 5 g of C
Poly(acrylic acid)-silica composites have been prepared by two different methods and thermally characterized. The glass transition temperature (T g ) of the PAA-SiO 2 system prepared by mixture method was found to be 120°C irrespective of the type and amounts of silica involved in this work. However
