Isocyanatoethyl acrylate

Polyurethane-acrylic coatings with interpenetrating polymer networks (IPNs) were synthesized from a two-component polyurethane (PU) and an unsaturated urethane-modified acrylic copolymer. The two-component PU was prepared from hydroxyethylacrylate-butylmethacrylate copolymer with or without reacting with c-caprolactonc and cured with an aliphatic polyisocyanate. The unsaturated acrylic copolymer was made from the same hydroxy-functional acrylic copolymer modified with isocyanatoethyl methacrylate. IPNs were prepared simultaneously from the two-polymer systems at various ratios. The IPNs were characterized by their mechanical properties and glass transition temperatures. 

The postintroduction of hydrophobes could offer an effective alternative to the mutual solubility problems (Chapter 20) encountered in chain-growth copolymerizations. The introduction of difunctional monomers that contain both unsaturation and isocyanate units (e.g., isocyanatoethyl methacrylate or m-isopropenyl a,a-dimethylbenzylisocyanate) with lower cost non-iso-cyanate-containing monomers (45) provides two routes for postmodification. One route could be the copolymerization with methyl acrylate, followed by the reaction of the isocyanate function with an ethoxylated surfactant, then hydrolysis of the methyl acrylate units.

Because of its relatively low boiling point HDI is currently only supplied in the form of derivatives (trimer, allophanate, biuret, etc) (18). Polyrmeric aliphatic isocyanates are obtained by copolymerization of 2-isocyanatoethyl methacrylate and styrene (19). Hydroxyalkyl acrylates and methacrylates are used as monomers to form hydroxyl group containing polymers, which are cross-hnked with diisocyanates or blocked diisocyanates (20). The elusive parent dusocyanate, 0=C=N—N=C=0, is only stable at —75°C, and therefore it is not suitable as a monomer or comonomer in polymerization reactions (21). 

The synthesis strategy for y/alcohols is depicted in Figurel 1,6a and 11.6b. 5/alcohols were converted into monomers or attached to polymer chains by several subsequent reactions. Etherification with allyl bromide resulted in allyl ethers [54] (Figure 11.6c). Phase transfer-catalyzed etherification of y/alcohols and p-(chloromethyl) styrene yielded y/styrene [35] (Figure 11.6d). By reaction with (meth)acryloyl chloride, sf (meth)acrylates were obtained, a method that was widely employed [36, 55, 56] (Figure 11.6e). Besides, the reaction of isocyanatoethyl (meth)acrylate with ... 

Crosslinking is an additional task for comonomers. N-methylol acrylamide fulfills this function in acrylic, vinyl acetate and styrene-butadiene latexes for textile binding. Glycidyl methacrylate can crosslink through reaction of its epoxide moiety with carboxyl or amino groups. Isocyanatoethyl methacrylate contains a reactive isocyanate group there are many others. 

Complex-forming POE/PAA interpenetrating polymer networks have been prepared by matrix polymerization of acrylic acid and ethylene diacrylate (a crosslinking agent) with a precrosslinked POE that was formed from hydroxyl-terminated POE and 2-isocyanatoethyl-2,6-diisocyanatohexanoate (131). At low degrees of POE crosslinking, dynamic mechanical properties in-...
