Low Waste And Environmentally Friendly Methods For Producing Polymers And Compositions
Abstract
Diols (glycols) are a class of organic compounds, the molecule of which contains two hydroxyl groups, these are dihydric aliphatic alcohols (the simplest glycol is ethylene glycol НО−СН2−СН2−ОН).The general formula for diols is CnH2n(OH)2. They are used in the production of polyester resins, polyurethanes, plasticizers, detergents, etc. Diols are one of the monomers to produce aliphatic and polyesters. Aliphatic polyesters are the polycondensation products of diols and aliphatic hydroxycarboxylic acids or aliphatic polycarboxylic acids. The general formula of dicarboxylic (dibasic) acids is НООС–(СН2)n–СООН. This class includes such acids as oxalic malonic, succinic, sebacic, adipic, cork, and others. Aliphatic hydroxycarboxylic acids are lactic, malic, tartaric, citric, and others. Complex polyesters are polycondensation products of diols and aromatic carboxylic acids. The article describes methods for producing aliphatic and aromatic polymers and compositions based on various diols of ethylene glycol, propylene glycol, butanediol, and others, with aliphatic hydroxy acids, aliphatic polycarboxylic, and aromatic acids, developed by domestic and foreign scientists.
