The reactive relationship between acrylics and alkyds has been defined by difficulty and an inability to propagate to form suitable grafting during a free-radical-based process. A living free-radical process was employed to provide control of both location and blocks of monomers which were attached to the polyester backbone of the alkyd. Both acrylic monomers and blocks of different monomer were successfully polymerized with control. Although there was some side reaction at the pendent fatty acid unsaturation, overall, the system was well behaved with respect to control of blocks of sequential monomers and living characteristics of the free-radical polymerization. Demonstration of concept was achieved in both high solids and waterborne systems. Representative coating properties are also reported for model alkyd systems.

A versatile, high-performance polyol chemistry for broad industrial market use / Jamie Dzickowski in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 208, N° 4647 (12/2018)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 208, N° 4647 (12/2018) . - p. 15-18 Titre : A versatile, high-performance polyol chemistry for broad industrial market use Type de document : texte imprimé Auteurs : Jamie Dzickowski, Auteur ; Sandra Case, Auteur ; Gianluigi Cassin, Auteur ; Jeremy Lizotte, Auteur ; Geoff Webster, Auteur Année de publication : 2018 Article en page(s) : p. 15-18 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Can coating Formulation (Génie chimique) Liants Polyesters Polyols Polyuréthanes Revêtements -- Additifs Index. décimale : 667.9 Revêtements et enduits Résumé : Polyester polyol chemistry has been used extensively as a binder option in high performance industrial coatings applications for decades. Limitations of traditional polyester technology, such as weathering and chemical resistance have restricted its use to a co¬binder due to the high level of performance requirements associated with these markets. Translating the use of a speciality monomer from copolyesters for thermoplastic applications, chemists at Eastman have evaluated the effectiveness of a unique glycol molecule as a building block in copolyester coatings resins targeted for use in automotive coatings, metal packaging applications for food cans and industrial applications like the agricultural and construction segment. Proven to enhance the hydrolytic stability and offer a balance of flexibility and hardness, the speciality polyol is enabling distinctive binder properties to address ever-changing global coatings needs. Fulfilling performance targets across very diverse fitness for use criterion, this paper capitalises on the versatility of the speciality polyol platform of resins.Through performance comparisons to next best alternative technologies, the improved durability will highlight the advantage of this next generation of polyol chemistry.
