VINYL ETHERS SYNTHESIZED FROM HYDROXYLATED VINYL

ETHERS AND POLYEPOXIDES

BACKGROUND OF THE INVENTION

Certain radiation curable coatings and films such as those formed from the acrylates, particularly propane trimethanol triacrylate, trimethacrylate, pentaerythritol triacrylate, and hexanediol diacylate or methacrylate, are in great demand because of their rapid curing properties.

Since acrylate compounds are not conducive to cationically induced radiation curing, they require more costly free radical systems which are oxygen inhibited unless effected in an inert atmosphere, generally under a blanket of nitrogen. Although formulation with a

photoinitiator which undergoes bimolecular reaction with a hydrogen donor minimizes the inhibitory effect of air, this benefit is realized at the expense of a greatly reduced cure rate. Also, it is found that polymerization or curing in free radical systems ceases almost immediately upon removal from the source of radiation; thus, the cured product likely contains significant amounts of

unpolymerized components. Accordingly, it is an aim of research to develop a compound having the beneficial properties of acrylates but which is amenable to radiation curing at a rapid rate by cationically induced

polymerization which is not oxygen inhibited and which permits continued polymerization after removal from the source of radiation exposure. THE INVENTION

According to this invention there is provided epoxy vinyl ethers having the formula

wherein R is a polyvalent linear, branched or cyclic hydrocarbon radical having from 2 to 20 carbon atoms, optionally substituted with alkyleneoxy; A is branched or linear C₁ to C₄ alkylene; B is halogen or lower alkyl; m has a value of from 0 to 4; n has a value of from 0 to

20; p has a value of from 1 to 5 and Y is when p is 1 and is or a mixture of

and -CH-CH₂OROCH=CH₂ when p is greater than

one. Of the above defined epoxy vinyl ethers, those wherein R is C₂ to C₆ alkylene, A is -CH₂- or

C(CH₃)₂, m has a value of 0; n has a value of from

0 to 12 are preferred. Most preferred of this group are the products wherein Y is and p is 1-5.

The method of synthesizing the above vinyl ethers (I) involves the reaction of a hydroxylated vinyl ether reactant, (HO)_pROCH=CH₂, and a diepoxy aryl

hydroxyalkyl ether coreactant.

wherein R, A, B, m, n and p are as defined. The mole ratio of reactants is critical and is the ratio where the number of epoxy groups in the reaction mixture exceeds the number of hydroxy groups in the

reaction mixture by at least one. Hence, where the

hydroxyvinyl ether reactant is (HO)₃ROCH=CH₂, the mole ratio of reactant to coreactant is between 1:2 and 1:3;

when (HO) ₅ROCH=CH₂ is substituted, the ratio is between 1:3 and 1:5 and when HOROCH=CH₂ is the reactant, the ratio is 1:1. In accordance with the species of products in this invention, the overall mole ratio of reactant to coreactant is from 1:1 to 1:5.

The reaction can be carried out in the presence of air or in the absence of oxygen under a blanket of inert gas. Generally, the present condensation reaction is carried out at a temperature of between about 100° and about 175°C. under atmospheric pressure for a period of from 0.5 to 200 hours. Preferred reaction parameters include a temperature of from about 120° to about 160°C. for a period of from about 2 to about 100 hours.

The reaction is also conducted in the presence of a base catalyst such as particulate sodium, potassium, or lithium metal, sodium or potassium hydroxide or hydride. The catalyst is present in an amount of from about 0.01 to about 2 wt. %, preferably from about 0.1 to about 1 wt. % of the total mixture. When the reactants and products included herein are liquids, they are generally synthesized in the absence of diluents or solvents which are otherwise required for more viscous or solid reactants.

Suitable hydroxylated vinyl ether reactants include the mono vinyl ether of cyclohexanetrimethanol, the monovinyl ether of cyclohexanedimethanol, the monovinyl ether of tris-(hydroxymethyl) ethane, the divinyl ether of 2-ethyl-2(hydroxymethyl)1,3-propanediol, the divinyl ether of tris(hydroxymethyl) ethane, tetra(hydroxyethyl) vinyloxy hexane, (2-hydroxyethyl) vinyl ether, (3-hydroxypropyl) vinyl ether, the monovinyl ether of 3-ethyl-1,6-hexanediol, (4-hydroxybutyl) vinyl ether, the monovinyl ether of

2-methyl-1,8-octanediol, (vinyloxy) cresol, (vinyloxy) xylol and alkoxylated derivatives thereof containing from 1 to 6 ethyleneoxy or propyleneoxy units. Suitable aromatic polyepoxy reactants include the terminally substituted diepoxy compounds of bisphenol A and bisphenol F, resins and compounds wherein one or more of the phenyl groups is substituted with halo or C₁ to C₄ alkyl radicals.

A commercially available group of diepoxy reactants suitable for use in the present reaction are the Epon epoxy resins supplied by Shell Chemical Company.

These resins have the following structure

These epoxy reactants are readily prepared by well known procedures, such as the procedure outlined on pages 10 through 21 of Chapter 2 of HANDBOOK OF EPOXY RESINS, by Henry Lee and Kris Neville, published by McGraw Hill Book Company, 1967.

These products are useful chemical intermediates and can be homopolymerized to hard chemically resistant films and coatings which have good substrate

substantivity. Alternatively, the present compounds can be mixed with alkenyl ether, alkenyl ester, epoxide or

acrylate monomers or polymers to impart rapid radiation curing properties in the presence of a cationic

photoinitiator. Cross-linking copolymerizations can be carried out in the presence of air to produce highly desirable films and coatings which retain the desirable properties of both monomers or their polymerized

derivatives. Curable compositions containing between about 0 and about 80% of a vinyl ether, an epoxide, an acrylate or a methacrylate comonomer or a polymer thereof and between about 20% and about 100% of the present epoxy vinyl ether in the presence of from about 0.05 to about 5 wt. % of a cationic photoinitiator are suitable radiation curable coatings which are polymerized by exposure to UV light, electron beam, laser emission or other source of

radiation. Between about 2 and about 50 wt. % of the present product with from about 0.1 to about 5 wt. % of a conventional photoinitiator, such as an onium salt

including the triphenyl sulfonium salt of phosphorous hexafluoride, diphenyl iodium salt, tetrazolium chloride, phenyl onium salts or aryl alkyl onium salts, cationic initiators and/or free radical initiators such as

1-hydrocyclohexyl phenyl ketone,

2-hydroxy-2-methyl-1-phenyl-1-propan-1-one,

2,2-dichloro-1-(4-phenoxyphenyl) ethanone and other free radical and cationic initiators which are suitably employed in this invention can be admixed with an acrylic compound normally not conducive to rapid cationic radiation curing, such as an acrylate or methacrylate comonomer, to effect curing within a few seconds exposure to a source of radiation. These coatings are applied to a substrate such as glass, ceramic, wood, plastic, metal and the like in thicknesses of from about 0.1 to about 5 mils.

Additionally, the compounds of this invention, because of their sensitivity to polymerization by radiation, find application as photoresist materials.

Curing of the present compounds or their admixtures with comonomers can be effected in less than 1 second by exposure to between about 100 and about 800 millijoules/cm² of UV light, between about 0.5 and about 5 megarads of electron beam exposure or equivalent

radiation exposures. According to another embodiment of this invention there is provided epoxy vinyl ethers having the formula

wherein R is a polyvalent linear, branched or cyclic hydrocarbon radical having from 2 to 20 carbon atoms, optionally substituted with alkyleneoxy; n has a value of from 1 to 20; p has a value of from 1 to 6; and at least one of Y and Y' is while each of any remaining Y and Y'can be - or -CHCH₂OROCH=CH₂. Of the

above defined polyphenyl vinyl ethers, those wherein R is C₂ to C₆ alkylene, n has a value of from 1 to 12 and Y and Y' are are preferred. Most preferred of this group are those compounds where n and p have a value of from 1 to 4.

The synthesis of the above epoxy vinyl ether (II) involves the reaction of a hydroxylated vinyl ether reactant, (HO)_pROCH=CH₂, and a polyepoxy aryl

hydroxyalkyl ether coreactant, of the formula

wherein R, p and n are as defined. The amounts of reactant and coreactant employed in the synthesis process to produce the epoxy polyphenyl product are critical. Specifically, the total number of

epoxy groups, with respect to the total amount of -OH groups in the system, must be in excess of at least one. For example, as an upper limit, when n is 20 and p is 1, there can be 21 epoxy GROUPS/OH. In the later case, where p is 1, only one epoxy group, of the original 22 epoxy groups, reacts. When a polyhydroxylated reactant is employed, e.g. (HO) ₃ROCH=CH₂, and n has a positive

value, e.g. 2, the ratio of reactant to coreactant is 1:1, whereby the product has one unreacted epoxy group; however when 2 moles of the coreactant to 1 mole of the reactant is employed, the product contains 5 unreacted epoxy groups. In another case where (HO) ₃ROCH=CH₂ is the reactant and n in the coreactant is 6, the ratio of reactant to

coreactant can vary from 1:0.5, where the product contains 1 remaining epoxy group, up to 1:1 where the product contains 5 remaining epoxy groups. Hence by controlling the amount of reactant to coreactant, or vice versa, all of the hydroxy groups of the hydroxylated vinyl ether will be reacted and the product will always contain at least one epoxy group. It is essential to retain an epoxy group in the product where derivatives of the present products are desired.

In accordance with another embodiment of this invention there is provided a fluorinated vinyl ether (III) having the formula

CF₃ (CF₂)_tR'OCH₂CHR"OCH=CH₂

wherein t has a value of from 1 to 22; R' is C₂ to C₂₀ alkylene, alkoxyalkylene, arylene or aryloxyalkylene which radicals are optionally fluorinated; R" is a divalent

radical having from 1 to 100 carbon atoms and is selected from the group of alkylene, arylene, alkarylene, aralkylene which groups are optionally substituted with lower alkyl or the radical

wherein R is a polyvalent linear, branched or cyclic

hydrocarbon radical having from 2 to 20 carbon atoms,

optionally substituted with alkyleneoxy; A is a divalent radical selected from the group of

where each of R₁, R₂, R₃ and R₄ is independently

hydrogen or

B is lower alkyl; m has a value of from 0 to 4 and n has a value of from 0 to 20.

The above compounds can be synthesized according to following equation A.

CF₃(CF₂)_tR'OH + CHR"OCH=CH₂ → CF₃(CF₂)_tR'OCH₂CHR"OCH=CH₂

l II wherein R', R" and t are as defined. When coreactant II is an oligomer, as described above for R", e.g.

1-[[[[2,3-epoxypropoxy]phenyl]alkyl]phenoxy]-3-[[vinyloxy] alkoxy]-2-propanol, the reaction can be illustrated by equation B below.

The synthesis is carried out under mild conditions such as a temperature of between about 50° and 160°C. under

atmospheric pressure for a period of from about 2 to about 50 hours, preferably at a temperature from 120° to about 150ºC. for a period of from 2 to about 10 hours. The reactants may be contacted in the absence or in the

presence of an inert solvent. When used, the solvent can be employed in an amount up to 70% of the reaction

mixture. Suitable solvents include, toluene, xylene, the dimethyl ether of tri- or tetra- ethylene glycol and the like. The reaction is carried out in the presence of between about 0.01 and about 3 wt. %, preferably between about 0.05 and about 1 wt. % of a base catalyst such as particulate sodium, potassium or lithium metal, a sodium, lithium or potassium hydroxide or hydride, and similar base catalysts. While the present reaction is not oxygen inhibited, it is preferred to conduct the reaction under a blanket of inert gas such as nitrogen. Examples of the vinyl ether epoxide reactant include [(vinyloxy) methyl] oxirane, [(vinyloxy) benzyl] oxirane, [(vinyloxy) phenyl] oxirane, [(vinyloxy) butyl] oxirane, [(vinyloxy) ethyl] oxirane, [(vinyloxy) octyl] oxirane, [(vinyloxy) dodecyl] oxirane, [(vinyloxy) tolyl] oxirane, [(vinyloxy)-2,3-dimethyl hexyl] oxirane,

[2-(vinyloxy) ethoxy] phenyl oxirane, and [[(vinyloxy) phenoxy]phenyl] oxirane.

Suitable fluoro alkanol reactants include pentafluoropropanol, pentafluorohexanol,

nonafluoropentanol, heptafluorodecanol,

heptadecafluorodecanol, pentadecafluorodecanol,

undecafluoroheptanol, 2-(undecafluorocyclohexyl) ethanol, heptatricontafluoroeicosanol, nonadecafluoroeicosanol, 2-(pentafluorophenyl) ethanol,

2-[4-(pentacosafluorododecyl) tetrafluorophenoxy] ethanol, etc.

Of the above named reactants,

pentadecafluorooctanol, heptadecafluorodecanol are

preferred flourinated alcohols. Preferred species of the oxirane reactant are [(vinyloxy) methyl] oxirane and the oligomers of equation B wherein n has a value of 0 or 1; m is zero; A is -C(CH₃)₂- and R is butylene.

The above compounds have been found to be excellent release coating materials. Accordingly, they can be coated on a suitable substrate such as glass, ceramic, wood, metal, woven fabrics, paper and the like in

thicknesses ranging from 0.05 up to 5 mils to provide products having stain and soil resistance or labels which are easily removed from paper surfaces or backing materials for adhesive tapes and the like and many other applications which are apparent from their properties. As coating agents, curing the products of the present invention is easily effected at room temperature under ambient pressure conditions by exposure to a source of radiation such as UV light, an electron beam, lazer emission and the like in the presence of from about 0.05 to about 5 wt. % of a

photoinitiator. Suitable photoinitiators are the onium salts such as the triphenyl sulfonium salt of phosphorous hexafluoride, diphenyl iodium salt, tetrazolium chloride, phenyl onium salts or aryl alkyl onium salts and the like. The amount of initiator employed is preferably between about 0.1 and about 2 wt. % with respect to reactants.

The present products can be cured in a period of less than 1 second, e.g. by exposure to between about 100 and about 800 millijoules/cm² UV light or between about 0.5 and about 5 megarads of electron beam emission. The sensitivity of the present compounds to radiation curing makes them excellent candidates for use as photoresists.

The products of this invention can also be cured by conventional thermal processes employing a temperature of from about 50°C. to about 160°C.
