Abstract:
A perfluoro group-containing epoxy compound of the formula wherein â€”A is a member selected from the group consisting of â€”OH, where y is an integer from 1 to 22, and â€”CzF2zâˆ’1 where z is an integer from 3 to 20, with the provisos that(1) when â€”A is â€”OH or â€”CzF2zâˆ’1, â€”Rfâ€” is a perfluoro group selected from the group consisting of â€”CH2â€”(CF2)mâ€”(CH2)nâ€” where m is an integer from 1 to 20 and n is 0 or 1, â€”CH2â€”(CF2)pâ€”C[â€”(CF2)qâ€”F][(CF2)râ€”F]â€”CH2â€” where p is an integer from 1 to 10, q is an integer from 0 to 22, and r is an integer from 1 to 22, â€”CH2â€”(CF2)sâ€”(Oâ€”CtF2t)uâ€”Oâ€”(CF2)vâ€”(CH2)wâ€” where s is an integer from 1 to 3, t is an integer from 1 to 4, u is an integer from 1 to 100, v is an integer from 0 to 3, and w is 0 or 1, where x1 is an integer from 0 to 10 and â€ƒis a perfluoro-cyclohexyl group, where x2 is an integer from 0 to 10 and â€ƒis a perfluoro-cyclohexyl group; and (2) when â€”A is â€ƒor â€”CyF2y+1, â€”Rfâ€” is a perfluoroalkyl group selected from the group consisting of â€”CH2â€”(CF2)sâ€”(Oâ€”CtF2t)uâ€”Oâ€”(CF2)vâ€”(CH2)wâ€”, where s, t, u, v, w, and are as defined above.
