Triethylene glycol divinyl ether

Maleate/vinyl ether formulations based on a model unsaturated polyester prepared from maleic anhydride and 1,5-pentane diol and triethylene glycol divinyl ether were studied. At molecular weights of less than about 10,000 the cured films were extremely brittle. When the equivalent weight of the unsaturated polyester was increased by replacing some of the maleic anhydride with succinic anhydride, measurable values for film elongation could be obtained but the cure speed was definitely slower. When either diethyl maleate or isobutyl vinyl ether were added as monofunctional diluents the cure dose needed to obtain 200 MEKDR was increased and the flexibility measured by pencil hardness increased as the amount of diluent was increased. A urethane vinyl ether was synthesized and used to replace DVE-3 and films with increased elongation were obtained at equivalent at dosages as low as 1 J/cm2. [Pg.131]

A wide variety of monovinyl and divinyl ethers are commercially available for this application, which allows the formulator greater latitude. For example, triethylene glycol divinyl ether [76-12-8] (DVE-3) and 1,4-cyclohexanedimethanol divinyl ether [17351-75-6] (CHVE) can be combined as reactive diluents, with each contributing quite different properties to the subsequently cured coating. CHVE offers hard brittle films, whereas DVE-3 produces films that have greater flexibility. DVE-3 is also a good solvent for the photoinitiator. More recently, the propenyl ether of propylene carbonate [130221-78-2] (PEPC) has been commercialized and specifically developed as a solubilizer for such initiators (68). Combinations of both divinyl ethers offer superior coatings that have controllable levels of flexibility, hardness, and solvent resistance (69). Their trade names are Rapi-Cure DVE-3, CHVE, PEPC, etc. [Pg.519]

The phases of -butylvinyl ether (C4VE) and -octadecylvinyl ether (C18VE) crosslinked with triethylene glycol divinyl ether or divinylbenzene were investigated by means of solid-state CPMAS NMR and HR MAS NMR in suspended-state. ... [Pg.260]

Comparisons with reference systems are also provided e.g. NDIO is a much better photoinitiator than the well known camphorquinone CQ (Table 1) upon a low intensity source (halogen lamp). This system leads to final tack-free coatings whereas no polymerization is observed with the CQ based system. TMPTA (trimethylol propane acrylate), EPOX ((3,4-epo>ycyclohexane)methyl 3,4-epo ycyclohe ylcarbo5ylate) and DVE-3 (triethylene glycol divinyl ether) are used as representatives of low viscosity monomers. Figure 6 shows that the synthesis of IPN (Fig. 6A epoxide and acrylate conversions 60%) or thiol-ene (Fig. 6B vinylether and trithiol conversions around 100 and 40%, respectively) is very efficient even upon a low intensity LED bulb.

Vinyl ethers add to the family of styrene-free unsaturated monomers for UPRs [173]. hi a study of UV-curable UPRs, triethylene glycol divinyl ether (Scheme 27), a member of the family of large vinyl ethers, was used. [Pg.66]

Scientists in basic cationic polymerisation chemistry have studied vinyl ethers for many years but, until recently, few monomers were available which gave products with useful properties e.g., triethylene glycol divinyl ether and cyclohexyl vinyl ether. Morflex has a range... [Pg.33]
