Monomers, polymers, preparation method and use thereof
Technical Field
The invention relates to the field of ophthalmic medical devices, in particular to a monomer and a polymer applied to a foldable artificial lens, a preparation method and application thereof.
Background
Ophthalmic medical devices, such as intraocular lenses, contact lenses, artificial corneas, intracorneal rings or intracorneal lenses, are artificial materials or lenses that can be implanted into the eye, mainly for replacing natural lenses in the eye that become cloudy due to diseases such as cataracts, or for correcting the vision of the eye by means of wear, refractive surgery, and the like. Such ocular medical devices are typically comprised of a circular optic and peripheral supports. Wherein, the optical part is made of transparent polymer material. Intraocular lenses made of soft polymers, also often referred to as foldable intraocular lenses, can be implanted into the eye through a small surgical incision after being folded or rolled, and can be automatically unfolded after entering the eye. Most of the current intraocular lenses are foldable intraocular lenses, and most of the soft materials used for preparing foldable intraocular lenses are poly (meth) acrylate polymers.
However, the polymers, monomers and methods for their preparation currently used for the preparation of ophthalmic medical devices are still in need of improvement.
Disclosure of Invention
The present application is made based on the discovery and recognition by the inventors of the following facts and problems:
the foldable artificial lens at present generally has the problem that the foldable artificial lens is difficult to implant through a small-size incision which can be realized by the current surgical technology. In particular, with the development of cataract surgery techniques, surgery through smaller incisions has been possible regardless of the size of the ocular medical device (e.g., intraocular lens) being implanted. However, it is difficult to realize the current medical device for eyes folded to the size that can be realized by the surgical incision under the condition of ensuring that the performance of the device is not affected. Thus, ophthalmic medical devices such as foldable intraocular lenses have somewhat hindered the performance of small incision procedures. The inventors have conducted extensive studies and extensive experiments to find that this is mainly due to the fact that the refractive index and mechanical properties of the polymers currently used for preparing ocular medical devices are difficult to meet the requirements. For foldable intraocular lenses, if optical properties of the foldable intraocular lens need to be guaranteed on the premise that the foldable intraocular lens can be folded to a smaller size, the material for preparing the intraocular lens is required to have better refractive index and mechanical properties at the same time: when the refractive index of the polymer for preparing the ocular medical device is not high enough, the requirement of the device on the optical performance needs to be met by increasing the thickness of the ocular medical device, and conversely, if the ocular medical device is required to have a sufficiently thin thickness, the polymer for preparing the device needs to have a sufficiently high refractive index; in addition, because the foldable intraocular lens needs to be automatically unfolded after entering the eye, the polymer for preparing the intraocular lens needs to have enough impact resistance, so that the intraocular lens cannot be broken off in the using process, and meanwhile, the polymer needs to have proper elasticity, so that the peripheral support can support the optical part to be stabilized in the eye without moving, and the damage to the eye caused by the excessively violent unfolding process is avoided.
The present invention is directed to solving, at least to some extent, one of the above technical problems in the related art. To this end, the invention proposes a monomer. The structure of the monomer is shown as the formula (I):
wherein the content of the first and second substances,
R1is hydrogen or methyl;
R2is an alkyl group;

n is 0, 1,2,3,4 or 5.
The polymer containing the monomer has higher refractive index and excellent mechanical property, and the polymer prepared by using the monomer has high refractive index, good transmittance and excellent mechanical property, is particularly suitable for preparing eye medical devices, and can meet the requirements of preparing thin and foldable artificial crystals.
The refractive index of the monomer and the polymer provided by the invention is not less than 1.53, and the spectral transmittance is not less than 80% in the visible light range of 400nm-800 nm.
The polymer provided by the invention has higher tensile strength, proper elastic modulus and larger elongation at break, and the foldable intraocular lens prepared by the polymer provided by the invention can not damage human eyes due to too violent opening and can not influence the use effect due to poor mechanical properties.

the compound shown in the formula (II) is obtained by carrying out substitution reaction on a compound shown in a formula (IV) and a compound shown in a formula (V),
wherein n and R1、R2And R3Having the definitions as described herein; r4is-Cl, -Br, -OTs or-OMs. The method has simple operation and high yield, and is particularly suitable for industrial scale-up production.

When the polymer is used for preparing the medical device for the eyes, the ideal device performance can be realized under the condition of smaller thickness, and the implantation of the medical device for the eyes can be realized by using smaller surgical incisions.

In one embodiment of the present invention, the ultraviolet absorber may include at least one of a copolymerizable benzotriazole-based compound and a copolymerizable benzophenone-based compound. In the present invention, the "copolymerizable benzotriazole-based compound" and the "copolymerizable benzophenone-based compound" are compounds containing a corresponding group (benzotriazole or benzophenone) copolymerizable with at least one of the above-mentioned monomers of the present invention (including the monomers proposed in the present invention and the compounds satisfying the formula (VI)), the initiator and the crosslinking agent. Those skilled in the art can select suitable compounds as the uv absorber within the above range depending on the actual situation, for example, the specific requirements of the ophthalmic medical device for the polymer. In one embodiment, the UV absorber can include 2- (2' -hydroxy-3 ' -methallyl-5 ' -methylphenyl) benzotriazole, 2- [3- (2H-benzotriazol-2-yl) -4-hydroxyphenyl ] ethyl 2-methacrylate, 2- (2H-benzotriazol-2-yl) -4-methyl-6- (2-propenyl) phenol, 2- (5-chloro-2H-benzo [ d ] [1,2,3] triazole) -4-methyl-6- (2-allyl) phenol, 4-allyl-2- (5-chloro-2H-benzo [ d ] [1, at least one of 2,3] triazole) -6-methoxyphenol, 2- (5-chloro-2H-1, 2, 3-benzo [ d ] [1,2,3] triazole) -4-methyl-6-allylphenol, 2-hydroxy-4- (methacryloyloxy) benzophenone, and 2- (4-benzoyl-3-hydroxyphenoxy) ethyl 2-acrylate. The ultraviolet absorbent added into the raw material of the polymer can absorb most of ultraviolet rays and prevent the retina of the eye from being damaged by exposure to the ultraviolet rays. The polymer added with the ultraviolet absorbent has the ultraviolet transmittance of 10 percent, the cut-off wavelength of not less than 360nm, the ultraviolet transmittance of the material in the range of less than the cut-off wavelength is lower, the maximum value of the visible light transmittance is not less than 80 percent, and the polymer has excellent ultraviolet light absorption capacity and visible light transmittance.

The refractive index of the polymer is not less than 1.53, and is greatly improved compared with the refractive index of the existing polymer for the ocular medical device, so that the thickness and the performance of the ocular medical device prepared by using the polymer can be obviously reduced. The polymers have high spectral transmittance in the visible light range. The polymer has higher tensile strength, proper elastic modulus and larger elongation at break, and the foldable intraocular lens prepared by the polymer provided by the invention can not damage human eyes due to too violent opening, and can not influence the use effect due to poor mechanical properties.
In a further aspect of the invention, the invention proposes the use of a polymer as described above for the preparation of an ophthalmic medical device. The polymer has high refractive index, good transmittance and excellent mechanical property, so that when the polymer is used for preparing the eye medical device, more ideal device performance can be realized under a smaller thickness, and the implantation of the eye medical device can be realized by using a smaller operation incision.

Thus, the use effect of the ocular medical device can be further improved.
In yet another aspect of the invention, the invention provides a method of making the aforementioned polymer. The method obtains the polymer by carrying out gradient heating treatment, namely gradient heating treatment on the raw material mixture. Wherein the feed mixture contains the monomers of the invention as set forth above. The specific types of the above monomers have been described in detail above and will not be described in detail here. In order to further improve the performance of the polymer prepared by the method, at least one of a cross-linking agent, an initiator and an ultraviolet absorber can be further included in the raw material mixture. The method has simple and convenient operation steps and short production period, and the obtained polymer has ideal refractive index.
In one embodiment, the gradient heat treatment may include:
a first reaction stage:
in the first reaction stage, the raw material mixture is heated to 40-70 ℃ for reaction, and the reaction time can be 1-24 hours. Thereby avoiding violent reaction and making the material more uniform.
And a second reaction stage:
in the second reaction stage, the raw material mixture after the first reaction stage is heated to 80-120 ℃ for reaction, and the reaction time can be 1-24 hours. Therefore, the conversion rate of the reaction raw materials can be further improved, and the material properties are more stable.

Determination of refractive index of Polymer
The refractive indices of the polymers obtained in examples 23 to 53 and 59 to 61 were measured under the following conditions: the refractive index of the material at a wavelength of 589nm was determined at 20 ℃ using an antopa DR-M2 refractometer.
The test results are shown in table 1. It can be seen from the data presented in the table that the following polymers all have high refractive indices, substantially greater than 1.53, and are well suited for use in the preparation of ophthalmic medical devices.
Table 1: refractive indices of the polymers obtained in examples 23 to 53 and 59 to 61
Determination of spectral transmittance of Polymer
The polymers obtained in examples 23 to 53 and 59 to 61 above were tested for their spectral transmittance under the following conditions: the spectral transmittance of the material in the light wave range of 200nm-800nm is tested by an Agilent Cary60 ultraviolet-visible spectrophotometer at room temperature.
The test results show that the polymers of examples 23-53 and 59-61 have maximum values of spectral transmittance higher than 80% in the visible light range. Table 2 shows the UV transmission cutoff wavelengths (wavelength corresponding to 1% UV transmittance and wavelength corresponding to 10% UV transmittance) and the spectral transmittances (maximum values) of the polymers A-1 to A-34. As can be seen from Table 2, the following polymers all have higher spectral transmittances. And the wavelength corresponding to the transmittance of 10% in an ultraviolet region is not less than 360nm, which shows that the following polymers have better ultraviolet light interception effect.
Table 2: spectral transmittances of the polymers obtained in examples 25 to 53 and 59 to 61
Determination of mechanical Properties of polymers
And (3) tensile test: the material was cut into a predetermined rectangular specimen (effective size: width 0.83300mm, thickness 0.40000mm, length 14.00000mm) with a cutter, and tested at room temperature of 26 ℃ and air humidity of 77% with an INSTRON 3367 type material tester, and the displacement rate was 500.00000 mm/min. Tests show that the following polymers have relatively good mechanical properties and are suitable for preparing artificial crystals. The following polymers have better spectral transmittance and refractive index, so that the following polymers can be conveniently used for forming the foldable artificial lens with thinness and good optical performance.
