Abstract:
UCST-type poly(N-acryloylglycinamide-co-acrylonitrile), which aggregates at a low temperature in aqueous solutions and dissolves at a high temperature, adsorbed moisture at high temperature (50 °C) and high humidity (p/p0 = 0.96), and the adsorbent was regenerated at a low temperature (5 °C) even at high humidity (p/p0 = 0.96). The thermoresponsible behavior was caused by the decrease in the glass transition temperature by the adsorbed water.

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...

Overview
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
Synthesis of carbohydrates
Sugar molecules are covalently linked together by dehydration synthesis. During the reaction, the hydroxyl (-OH) group from...
