Definitions
- This invention relates to the use of macromer-forming catalysts in the formation of macromers, especially the macromers used to make ophthalmic lenses.
- Ophthalmic lenses such as contact lenses are often made in polymerization processes which employ initiators.
- Acylphosphine oxides are a useful class of initiators for free radical polymerizations of the type frequently used to make ophthalmic lenses.
- Bisacylphosphine oxides and their use are described in US Patent No. 5,534,559 incorporated herein by reference. All of the patents and patent applications listed herein are incorporated by reference.
- the prior art macromer-forming catalysts which are used in the preparation of the macromers, which are used to make ophthalmic lenses often adversely effect the stability of these initiators and the use shelf life of the multicomponent formulations which contain them.
- Stability of the initiator can effect the shelf life of the monomer mix. Increasing the "shelf life" or stability of the monomer mix from that seen in the prior art is desirable since it reduces the need to frequently prepare monomer mix lots (as described below) and the possibility of introducing lot to lot and intra-lot variations in lens production.
- EP 849,296 proposed a method of stabilizing bisacylphosphine oxide initiators used in the production of urethane (meth)acrylate polymers used for optical fiber coatings. The method involves preparing a urethane (meth)acrylate oligomer using a tertiary amine catalyst and then mixing with the photoinitiator and other coating formulation components. There are also similar methods in the prior art of stabilizing monoacylphosphine oxide photoinitiators in the presence of a tin compound used as a macromer-forming catalyst in the urethane (meth)acrylate oligomer synthesis.
- U.S. Patent Application No. 01/09076 teaches the use of tin catalysts with acetic acid.
- a tin catalyst such as dibutyl tin dilaurate (DBTDL) is not desirable when applied to monomer mixes used to make ophthalmic lenses because of the potentially deleterious effect it has on the photoinitiator and may have on various other components of the monomer mix. This is particularly true where the monomer mix is used to make silicone hydrogel lenses.
- DBTDL dibutyl tin dilaurate
- the prior art teaches the use of Lewis acid catalysts, including, but not limited to, tin catalysts, such as DBTDL for the formation of macromers.
- tin catalysts such as DBTDL

- Macromer-forming Catalysts macromer-forming catalysts, which catalyze the attachment of reactive polymerizable groups to a macromer, from electrophilic compounds and macromer-precursor materials, (“Macromer-forming Catalysts"), and which include, but are not limited to, tertiary amines, preferably triethylamine (“TEA”), and bismuth catalysts
- the present invention relates to composition of matter comprising: a macromer formed from an electrophilic compound and a macromer-precursor material in the presence of a macromer- forming catalyst; combined with a visible light photoinitiator, wherein the macromer-forming catalyst is compatible with the photoinitiator.
- Figure 1 is a graph showing the change in enthalpy of photopolymerization with aging for three different monomer mixes, one with a triethylamine (“TEA”) catalyzed macromer, one with a DBTDL catalyzed macromer and one with a K- KAT 348 bismuth carboxylate catalyzed macromer.
- TAA triethylamine
- macromer-forming catalysts are catalysts that catalyze the reaction (preferably Lewis bases) but are compatible with visible light activated photoinitiators, such that they do not adversely affect the concentration of the photoinitiator after mixing into the monomer mix, maintaining a desired shelf life.
- the macromer-forming catalysts include, but are not limited to, amines, pyridines, sodium hydroxides, sulfuric acids, trifluoro acetic acids, bismuth salts and tertiary amines.
- the electrophilic compound has the following structure
- RG-LG-PG where RG comprises a reactive group, which may be selected from the group comprising electrophilic functional groups including, but not limited to, isocyanate, acid halide, acid anhydride, ester, epoxide, acetal, aldehyde, alkyl halide (preferably an activated alkyl halide).
- LG comprises a divalent linking group, including, but not limited to, an alkyl, aryl, ester or ether group or a covalent bond.

- the macromer-precursor may also comprise chemical groups that contribute to high oxygen permeability such as siloxane groups such as polydimethylsiloxane groups, or polyfluorinated groups.
- the macromer-precursor may also comprise hydrophilic groups such as hydroxyls (in excess of those needed to react with the electrophile), amide or ether groups such as polyethylene oxide groups. Such hydrophilic groups may contribute to the formation of optically clear solutions of silicone and hydrophilic monomers used in the monomer mix.

- One of the major benefits of using the claimed macromer-forming catalysts in the macromer synthesis is that the initiator subsequently used in the polymerization process is not adversely affected. Additionally, any of the macromer-forming catalysts can be adjusted in amount to give acceptable reaction time in the macromer formation.

- photomitiators can be used alone or in combination with other initiators, including, but not limited to, benzoin methyl ether, 1-hydroxycyclohexyl phenyl
- HMPP hydroxy-2-methyl-l-phenyl-propan-l-one
- BDK 2,2-dimefhoxy-2- phenylacetophenone
- HMPP propan-1-one
- the following examples compare the ophthalmic lenses prepared from the present invention to those prepared according to the prior art. Notably, the lenses prepared according to the present invention are acceptable for use and are equivalent to the reference lenses.
- TMS-HEMA, MMA, mPDMS (about 800 to about lOOOMW), TRIS, p-xylene and tetrahydrofuran (THF) were dried over preactivated 4A molecular sieve, and THF, mPDMS, and TRIS were passed through aluminum oxide column before use.
- TBACB tetrabutylammonium 3-chlorobenzoate
- step 2 a mixture of TMS-HEMA (2.1 eqv. to initiator), mPDMS (3.3 eqv. to initiator), TRIS (7.9 eqv. to initiator) and bis(dimethylamino)-methylsilane, prepared in dry box, was added under nitrogen.
- step 3 a mixture on of TMS-HEMA (8.5 eqv. to initiator), MMA (1.4 eqv. relative to initiator) and bis(dimethylamino)-methylsilane was added and the whole mixture allowed to exotherm to 46 - 49°C. After the mixture reacted about two hours, 270 g of THF was added to reduce the viscosity and the solution was stined for additional 30 minutes.
- step 4 a mixture of water, methanol and dichloroacetic acid was added and the mixture was refluxed for five hours to de-block the protecting groups. The solvents were then removed by distillation and toluene was added to aid in removal of residual water until a vapor temperature reached 110°C. A solution of TMI and 0.2 mole % bismuth catalyst K-KAT 348 relative to TMI was added to the above solution in toluene. The whole mixture was stined at 110°C for three hours and the disappearance of the isocyanate peak was monitored by IR. The toluene was removed under reduced pressure at around 45°C to give a raw macromer.
- a bismuth catalyst and a TEA catalyst were each separately used to synthesize the macromer (as described in Example 1), which was later used to make ophthalmic lenses.
- the lenses were made via direct molding, using a closed mold under conventional molding conditions. These lenses were compared.
- the lenses were optically clear.
- the bismuth catalyst macromer has at least a 10-
- the TEA catalyzed macromer has at least a 30-week shelf-life at 55°C.
- DBTDL catalyzed macromer also uses acetic acid in the formation process as described in U.S. Patent Application Serial No. 01/09076.
- the elastic modulus values for lenses from DBTDL-catalyzed macromer were comparable to the modulus for lenses from TEA-catalyzed monomer, but the DBTDL-catalyzed macromer lenses were unacceptable to wear because they were misshapen and had torn or jagged edges..
- Acceptable modulus values are about 30 to about 200 psi, more preferably about 35 to about 150 psi, and most preferably about 38 to about 100 psi.
- Table 3 reflects the measurements of relevant characteristics for the average of 8 batches using TEA-catalyzed macromer in monomer mixes and the average of 3 batches using DBTDL-catalyzed macromer in monomer mixes.
- a monomer mix was made from macromer, which was made as described in Example 1, by combining the following: 17.98 % (wt) macromer from Example 1, 28.0% mPDMS (MW 800-1000), 14.0% TRIS, 26.0% DMA, 5.0% HEMA, 1.0% TEGDMA, 2.0% Norbloc (2-(2'-hydroxy-5-methacrylyloxyethyl ⁇ henyl)-2H- benzotriazole), 0.02% Blue HEMA (product of the base-promoted displacement of one chloride of Reactive Blue # 4 dye by hydroxyethyl methacrylate), 5.0% PVP (K90), and 1.0% CGI 1850 (1:1 (wt) blend of 1-hydroxycyclohexyl phenyl ketone and bis(2,6-dimethoxybenzoyl)-2,4-4-trimethylpentyl phosphine oxide) blended with the diluent 3,7-dimefhyl-3-octanol in a ratio of 80 parts
- the enthalpy of photopolymerization was measured using a TA Instruments differential photocalorimeter with a mercury vapor lamp, with the sample at 70°C under a nitrogen atmosphere.
- the enthalpy of photopolymerization was measured as a function of monomer mix storage time at 55°C.
- the results are shown in Figure 1, showing monomer mixes made using macromer made using the procedure of Example 1 with the following macromer-forming catalysts: TEA, DBTDL (with acetic acid) or K-KAT 348 bismuth carboxylate catalyst.
- the enthalpy values are the average of two measurements each.
- Enthalpy values for monomer mixes made using TEA or K-KAT 348 are statistically equivalent and do not exhibit a decrease over time as compared to monomer mixes made using DBTDL in the prior art. Without being limited to the mechanism, the degradation of the enthalpy values for the monomer mixes made using DBTDL represents degradation of the visible-light photoinitiator.
- Example 5
- a monomer mix was made from the following: 17.98 % (wt) macromer from Example 1 but made with DBTDL in place of K-KAT 348 bismuth carboxylate catalyst, 28.0% mPDMS (MW 800-1000), 14.0% TRIS, 26.0% DMA, 5.0% HEMA, 1.0% TEGDMA, 2.0% Norbloc (2-(2'-hydroxy-5- methacrylyloxyethylphenyl)-2H-benzotriazole), 0.02% Blue HEMA (product of the base-promoted displacement of one chloride of Reactive Blue # 4 dye by hydroxyethyl methacrylate), 5.0% PVP (K90), and 1.0% CGI 1850 (1:1 (wt) blend of 1-hydroxycyclohexyl phenyl ketone and bis(2,6-dimethoxybenzoyl)-2,4-4- trimethylpentyl phosphine oxide) blended with the diluent 3,7-dimethyl-3-octanol in
- contact lenses were made by curing in plastic molds under inadiation for 30 minutes with visible light fluorescent bulbs
- lenses were released in 60% IPA in water, then soaked at least one hour each in 100%, 75%), 50% and 25% (v/v) IPA in water.
- the resulting lenses were round and symmetrical, and had smooth optical surfaces.
- lenses made from aged monomer mix were asymmetrical, and had rough and unacceptable optical surfaces.
- lenses made with the same process from a monomer mix with a bismuth catalyzed macromer were symmetrical and had smooth optical surfaces even when made from a monomer mix stored for 4 weeks or longer
