## Abstract Sulfonated dimethyl fumarate (SDMF) was prepared. Poly(ethylene oxide) (PEO) with sodium sulfonate side chains (SPEO) was synthesized by transesterification between SDMF and PEO with molecular weights of 200, 400, 600, 800, and 1000. The SPEO was subsequently mixed as a plasticizer with

## Abstract In this study, a series of aqueous polyurethane modified by poly(dimethyl siloxane) PDMS were synthesized, which were based on polyoxytetramethylene glycol (PTMG), isophorone diisocyanate (IPDI), dimethylol propionic acid(DMPA), and PDMS. The copolymer was characterized by FTIR and the
Ab initio and DFT calculations performed on the title systems revealed two types of structures for both DMDS-HNO 3 and DMDO-HNO 3 complexes. In both structures two hydrogen bonds are formed between the OH group interacting with one of sulfur (or oxygen) atoms and methyl CH group being a proton donor
