Unsaturated alcohols and glycols containing ionizable groups for synthesis of urethane acrylate graft copolymer latices

Abstract

Unsaturated alcohols and glycols bearing carboxylic groups were synthesized from maleic anhydride (MA) and alcohols with 2 or 3 hydroxy groups. The halfester monomers were characterized by IR and NMR spectroscopy and were used for the preparation of urethane macroionomers and urethane acrylate graft copolymer latices. Obtained polymers were characterized by solubility and mechanical tests. ZUSAMMENFASSUNG:Ungesattigte Alkohole und Glykole mit Carbonsaure-Gruppen wurden durch Umsetzung von MaleinsBureanhydrid und Alkoholen mit 2 oder 3 Hydroxygruppen hergestellt und durch IR-und NMR-Spektroskopie charakterisiert. Maleinsaurehalbester wurden fiir die Vorbereitung von Urethan-Makroionomeren verwendet. Durch radikalische Polymerisation dieser Ionomeren wurden Acrylat-Pfropfpolymere mit Urethanseitengruppen erhalten, deren Uslichkeit und mechanische Eigenschaften bestimmt wurden.

Micromorphology and phase behavior of cationic polyurethane segmented copolymer modified with hydroxysilane

“…For example, Stefano Fiori successfully schemed out a frontal polymerization method [11]; John Texter developed a micro-emulsion polymerization method [12]. And various WPU/acrylic hybrid dispersions had been studied and developed through different routes, such as seeded emulsion polymerization [13,14], forming interpenetrating polymer networks (IPN) or semi-IPNs [15][16][17], crosslinking [18], and graft copolymerization of PU onto acrylic polymer chains [19][20][21][22][23] and so on.…”

Waterborne UV/EB curing systems

“…Structural core-shell polymers found themselves very interestingly applied in waterborne coating chemistry, especially for redispersible polymer powders preparation [9][10][11]. The chance to have a polymer in a powder form instead of an aqueous dispersion is more profitable either from an economical and enduser point of view [10][11][12].…”

Effect of Incorporating a Diurethane Monomethacrylate Monomer into Acrylic Latexes

“…The addition of urethanes to acrylics has shown to enhance the overall properties of the coatings such as excellent toughness, improved chemical resistance, and abrasion resistance. − Waterborne polyurethanes (PUD)­s are dispersions with a relative high molecular weight that do not usually mix well with acrylics. − There is an increasing interest to blend PUDs and acrylic latexes, combining the superior properties of polyurethanes with polyacrylates, thus lowering cost . Consequently, different approaches have been developed to eliminate this issue, including grafting, − interpenetrating polymer networks (IPNs), − PUD seed − and acrylic carbamate monomers. − …”
