Definitions
- the present invention relates to a urea (meth)acrylate or urea-urethane (meth)acrylate oligomer, to polymerizable compositions comprising, and its uses, in particular as a binder in a polymerizable composition, in particular in an ink composition, a coating composition, a material filled with fibrous or particulate reinforcements which may be carbon nanotubes or graphite, an adhesive composition , molding, ink plate, electrode binder, and in a composition for additive manufacturing, in particular for printing 3D or 4D objects.
- urethane acrylates of high functionality by reacting an amine with an acrylate, then adding the aminoacrylate obtained to an isocyanate.
- WO 2007/005351 describes liquid compositions of self-photoinitiating multifunctional acrylate urethane oligomers having pendant acrylate groups and tertiary amine groups integrated into the polymer backbone, obtained by the reaction of two oligomer molecules comprising primary hydroxyl groups with the terminal isocyanate groups of a tertiary N-bis-urethane aminoacrylate oligomer.
- WO 2016/170264 describes an aminoacrylate-acrylate urethane comprising a urethane function linked to an aminoacrylate group, the latter carrying one or more acrylate groups and deriving from a) a hydroxylated aminoacrylate carrying one or more acrylate groups with b) a polyisocyanate, the aminoacrylate a) being the addition product of a1) an aminoalcohol carrying a hydroxy group and a secondary amine group on a2) a multifunctional acrylate, with a2) being in excess stoichiometric with respect to the secondary amine groups of the aminoalcohol a1).
- the urethane acrylates of the prior art are obtained from secondary amines, which involves the formation of a large quantity of tertiary amine before the addition of the isocyanate, the tertiary amine functions being moreover useful for catalyzing the desired urethanization reaction. It turns out, however, that tertiary amines are sensitive to certain chemical attacks (acids) and become colored (yellowing) during crosslinking under UV. Furthermore, the preparation of these urethane acrylates requires prolonged heating at high temperature and the use of toxic metal catalysts, such as tin-based catalysts.
- the present invention seeks to overcome the drawbacks of the urethane acrylates of the prior art by eliminating the presence of tertiary amines before the addition of isocyanate.
- the inventors have therefore modified the urethane acrylate nature of the final oligomer into urea (meth)acrylate or urea-urethane (meth)acrylate.
- the solution proposed by the inventors is based on the reaction between an isocyanate and a secondary amine to form a urea, without requiring the presence of any catalyst. More particularly, the proposed solution consists in the use of a compound comprising simultaneously at least one secondary amine function and at least one (meth)acrylate function.
- the urea (meth) acrylate or urea-urethane (meth) acrylate oligomer of the invention makes it possible to achieve the following technical advantages compared to urethane acrylates of the prior art: - the absence or the very low content of tertiary amine leading to a very good stability of the color of the oligomer after crosslinking (absence of coloring, no yellowing), - overall properties of the oligomer equivalent or superior to urethane acrylates, but without the presence of secondary products linked to the consumption of stabilizer and to the more severe thermal conditions of synthesis (higher purity of the oligomer of the invention), - resistance to abrasion improved, - better viscosity/hardness compromise than urethane acrylates, the urea function being harder and more viscous than the urethane function of urethane acrylates, - simpler, faster, safer and more economical synthesis, due to the absence prolonged heating (the reactor can simply be maintained at the desired temperature thanks to the

- Example 9 Preparation of an aminoacrylate-acrylate urethane oligomer according to WO 2016/170264 (comparative example) HDDA SR238 (75.00 g), EMHQ (0.100 g), BHT (0.050 g ), triphenylphosphite (0.100 g) and PTZ (0.020 g) were introduced at 23oC into a reactor equipped with a reflux column, two dropping funnels, a thermometer and a stirrer with inclined blades . NMEA (17.80 g) was introduced through a dropping funnel over a period of 30 minutes. The reactor was heated to 50°C in 30 minutes and then maintained at this temperature for 2 hours.
- Example 10 Preparation of a urea (meth)acrylate oligomer according to the invention HDDA SR238 (75.00 g) and EMHQ (0.120 g) were introduced at 23° C. into a reactor equipped with a reflux column, two funnels, a thermometer, and a stirrer with inclined blades. Sec-butylamine (17.33 g) was introduced through a dropping funnel over a period of 5 minutes. The reactor was heated to 55°C for 10 minutes, then to 75°C and maintained at this temperature for 1 hour. The reactor was then cooled to 40°C.
- IPDI (21.95 g) was added through the second dropping funnel over a 1 hour period. During the introduction, the temperature was maintained at a temperature below 50oC by controlling the exotherm with an ice water bath. The temperature was maintained at 50°C for 15 minutes.
- Examples 11 to 13 Preparation of urea (meth)acrylate oligomers according to the invention The same protocol as in example 10 was repeated by modifying the proportion and the nature of the amine and of the isocyanate as shown in Table 3 below. [0154] [Table 3] The molar quantity of isocyanate functions introduced was constant in all the examples of Table 3, so that the latter are strictly comparable.
- Example 11 shows that mechanical properties equivalent to those of the reference can be obtained without the presence of a cycle.
- the comparison between Examples 9 and 11 is proof that the urea function present in the oligomer of the invention is preferable to a urethane function, at an equivalent concentration.
- the invention offers the possibility of synthesizing oligomers having isocyanate/amine R2 ratios close to 1, which is not possible for the reference.
- examples 12 and 13 show that the compromise between viscosity and Persoz hardness is very clearly to the advantage of the oligomers of the invention.
- Example 14 Preparation of an intermediate with secondary diamine 2(2-ethoxyethoxy)-ethyl acrylate SR256 (60.00 g) and EMHQ (0.100 g) were introduced at 23° C. into a reactor equipped with a reflux column, two funnels, a thermometer and a stirrer with inclined blades. 4,4'-methylenebis(cyclohexylamine) (33.51 g) was introduced through a dropping funnel over a period of 5 minutes. The reactor was heated at 90°C for 3 hours. The reactor was then cooled to 65° C., then HDDA (20.00 g) was introduced through the other dropping funnel over 5 minutes. The reactor was then maintained at 65°C for 1 hour and then cooled to ambient temperature.
- Example 15 Preparation of an HDI-pentaerythritol triacrylate adduct intermediate HDI (29.66 g), BHT (0.050 g) and EMHQ (0.050 g) were introduced at 23° C. into a reactor equipped with a reflux column, a dropping funnel, a thermometer and a stirrer with inclined blades. Pentaerythritol triacrylate SR444D (91.69 g) was added through the dropping funnel over 20 minutes. The reactor was heated to 80°C until an isocyanate index of 82 mgKOH/g was obtained. After cooling to room temperature, the intermediate is kept for 30 minutes (it is never kept for more than 24 hours).
- Example 16 Preparation of a urea-urethane (meth)acrylate oligomer according to the invention 50.00 g of the intermediate with secondary diamine prepared in Example 14 and BHT (0.100 g) were introduced at 23oC in a reactor equipped with a reflux column, a dropping funnel, a thermometer and a stirrer with inclined blades. The reactor was heated to 50°C until complete solubilization of the BHT. 96.54 g of the HDI-pentaerythritol triacrylate adduct intermediate prepared in Example 15 were introduced through the dropping funnel over 30 minutes.
- Example 17 Preparation of a urea-urethane (meth)acrylate oligomer according to the invention Under dry nitrogen bubbling at a flow rate of 20 mL/minute, DEM (28.21 g) was introduced at 23oC into a reactor equipped with a reflux column, two funnels, a thermometer and a stirrer with inclined blades.
- Example 18 Preparation and Evaluation of Polymerizable Compositions Based on Urea (meth)acrylate Oligomers According to the Invention Compositions were prepared from the urea (meth)acrylate oligomers of Examples 1, 2 and 3 of invention. The oligomers were preheated to 65°C, then, with manual stirring, a photoinitiator was introduced and dissolved. The mixtures were then left to come to room temperature (25°C). The compositions appear in Table 5 below (the amounts are indicated in grams).
