(a-1) obtained by reacting a polyol prepared by the addition of bisphenol A with an alkylene oxide with both an aliphatic polycarboxylic acid and an aromatic polycarboxylic acid, a crystalline polyester polyol (a-2), and a polyoxyethylene glycol (a-3) having a number-average molecular weight ...
Non-biofouling surfaces constitute one of the most important subjects in sensitively and selectively detecting biomolecular events. Poly(ethylene glycol) (PEG) chains tethered on substrate surfaces are well known to reduce non-biofouling characteristics.
Oxirane (ethylene oxide) polyurethane coatings 来自 Semantic Scholar 喜欢 0 阅读量: 18 作者: P·A·爱德华兹 摘要: The present inventaion relates to hydrophilic, i.e., water loving coatings (hereafter referred to as 'WLC'). Polyurethane epoxy alkylene oxide coatings usable as coatings on ...
depending upon the PVA grade (degree of hydrolysis and pH). In order to improve thethermal stabilityand processing properties of PVA, the use ofplasticizersis required. Various plasticizers such as water, glycerol,ethylene glycol, and its dimer and trimer, amine alcohols, and polyvalent hydroxyl ...
An oxyalkylated product useful for making polyurethane foams is prepared by reacting an alkylene oxide with a heated mixture of a phenol and a non- phenolic active hydrogen compound, at least one of which can be halogenated, in the presence of a catalyst complex of a phenol and an iron or...
alkylene oxide with a compound having at least one active hydrogen atom up to as many as six such active hydrogen atoms including, for example, water, monohydroxylic alcohols such as ethanol and propanol, dihydroxylic alcohols such as ethylene glycol, trihydroxylic alcohols such as glycerine and...
700-3500, obtained by reacting one or more of the following acids: succinic, glutaric, adipic, pimelic, suberic, azelaic or sebacic acids, optionally subsituted by one or more methyl groups with one or more of the following diols: ethylene glycol, 1,2- or 1,3-propanediol, 1,2-, 1,...
