Alkyd resins are amongst the most important and widely used resins in coating sectors. In this communication we report on preparation of alkyd resins emulsified by grafted acrylic resins on their fatty acid moieties. Both high-shear mechanical homogenizer and ultra-sonic sonicator were used step-wise to disperse the alkyd resin and acrylic based monomers in aqueous media. The resins are of nano...

Alkyd resin merupakan produk polimer yang banyak digunakan dalam industri cat, coating, dan pembuatan film. Hal ini dikarenakan keunggulan sifat – sifatnya sebagai surface coating meliputi fleksibilitas, kekuatan durabilitas, serta adhesi baik. Penelitian membuat alkyd berbasis palm fatty acid distillate (PFAD) urea formaldehide terbutilasi dengan variasi rasio molar butanol 0,5-3 mgrek/mgrek. ...

For a purified preparation of the soluble form of phosphatidate phosphohydrolase (EC 3.1.3.4) from guinea pig cerebral cortex, I-O-alkyl-racglycerol 3-phosphate was found to be accepted as a substrate. This substrate analog was tritium-labeled in order to serve in a rapid sensitive assay for the enzyme, in which labeled I-alkyl glycerol is released. Heat denaturation and enzyme activity depende...
