Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : In spite of growing demand for water based paints, no properly documented Size Exclusion Chromatographic method for studying molecular weight distribution of emulsion polymers is available in literature, and hence, in the light of this, a simple, quick and reproducible method has been proposed for the molecular weight determination of all acrylic and styrene acrylic emulsion polymers. The emulsion sample is dissolved in tetrahydrofuran and injected into a mixed bed column. Distributed species are detected through a high range refractive index detector and PL logical software is used to compute molecular weight distribution related data. Polystyrene standards are used to plot a calibration curve. The selection of polymer peak limits is done manually. Various experimental factors related to sample preparation and chromatographic conditions which affect reproducibility are carefully studied before arriving at the proposed method.

Titre : Effect of modification with cardanol-formaldehyde resin on the quality of rubber seed oil and its alkyds as binders in surface coatings Type de document : texte imprimé Auteurs : A. I. Aigbodion, Auteur ; C. K. S. Pillai, Auteur ; I. O. Bakare, Auteur ; L. E. Yahaya, Auteur Année de publication : 2001 Article en page(s) : p. 39-42 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The effects of modification with cardanol-formaldehyde (CF) resin on the dyeing schedule and chemical resistance of rubber seed oil (RSO) and its alkyds were investigated. Cardanol was obtained by vacuum distillation of commercial grade cashew nut shell liquid (CNSL) conforming to India Standard IS 841-1964. Raw RSO and its alkyds of different oil lengths were blended with CF resin in a ratio of 9:1 by heating at 200°C for 1h and the products obtained therefrom were tested for drying time and chemical resistance. Rubber seed oil is naturally semi-drying and modification with CF resins improves its drying ability, as it was able to air-dry to a hard film upon modification. Similarly, modification with CF resin greatly enhanced the drying rate and chemical resistance of RSO alkyds. The potentials of both RSO and CNSL as renewable resources could be exploited as raw materials for the Nigeria surface coatings industry. Note de contenu : - Preparation of the alkyds
