DOI: 10.1002/app.44927
Abstract: Poly(siloxane–ether–urethane)-acrylic (PU-AC) hybrid emulsions were prepared by introducing different hydroxyethoxypropyl-terminated polydimethylsiloxane (PDMS) content into the acrylic-terminated poly(ether-urethane) backbone and then in situ copolymerizing with methyl methacrylate and butyl acrylate via emulsion process. The effects of… read more here.

DOI: 10.1002/pi.5333
Abstract: A series of new bio-based aromatic diisocyanates, namely bis(4-isocyanato-2-methoxyphenoxy)alkane and bis(4-isocyanato-2,6-dimethoxyphenoxy)alkane, were synthesized starting from lignin-derived phenolic acids, namely vanillic acid and syringic acid, via the Curtius rearrangement. The diisocyanates were employed to synthesize poly(ether… read more here.
