Abstract
Sposób wedlug wynalazku polega na tym, ze polihydrometylosiloksan (PHMS) lub poli(hydrometylosiloksan-ko-dimetylosiloksan) (PHMSDMS) o ogólnym wzorze: R(CH3)2SiO[(CH3)HSiO]p[(CH3)2SiO]rSi(CH3)2R, gdzie R oznacza grupe alkilowa, korzystnie metylowa, lub wodór, p jest liczba naturalna od 5 do 200, korzystnie od 20 do 50, r stanowi zero lub liczbe naturalna od 5 do 200, korzystnie od 20 do 50, stosunek r/p jest równy od 0 do 10, korzystnie od 0 do 2, poddaje sie wstepnej katalitycznej reakcji hydrosililowania oligomerem siloksanowym o wzorze: R2(CH3)2 SiO[(CH3)2 SiO]s[CH3(CH=CH2)SiO]tSi(CH3) 2R2, w którym R2 oznacza grupe winylowa -CH=CH2 lub metylowa, do zawieszenia na nim oligomeru z grupa winylowa, ale bez jego usieciowania, a nastepnie razem z katalizatorem platynowym hydrosililowania, w rozpuszczalniku mieszajacym sie z woda, przenosi sie go do wody zawierajacej surfaktant z wytworzona emulsja, w której prowadzi sie wytwarzanie mikrosfer, sieciujac polimer w wyniku procesu hydrosililowania, z jednoczesnym wytwarzaniem grup SiOH, po czym wydzielone z emulsji hydrofilowe mikrosfery, ewentualnie poddaje sie modyfikacji przez poddanie ich reakcji z reaktywnymi silanami o ogólnych wzorach: (CH3)m[X(CH2)n]SiY3-m i/lub (CH3)m[CH3(CH2)n']SiY3-m, w których X oznacza grupe funkcyjna, wybrana z grupy obejmujacej grupe aminowa, N-alkiloaminowa, 1,2-NN'-etylodiaminowa, diarylophosphinowa, halogenowa, tiolowa, epoksydowa, glicydoksylowa, metakrylowa, imidazolowa, pirydynowa, oksymowa lub izocyjanianowa, Y jest grupa alkoksylowa, korzystnie metoksylowa lub etoksylowa, a gdy grupa funkcyjna X nie ma wlasnosci zasadowych halogenem, najkorzystniej chlorem, lub grupa acyloksylowa. The method according to the invention consists in the polyhydromethylsiloxane (PHMS) or poly (hydromethylsiloxane-co-dimethylsiloxane) (PHMSDMS) with the general formula: R (CH3) 2SiO [(CH3) HSiO] p [(CH3) 2SiO] rSi (CH3) 2R, where R is an alkyl group, preferably methyl or hydrogen, p is a natural number from 5 to 200, preferably from 20 to 50, r is zero or a natural number from 5 to 200, preferably from 20 to 50, ratio r / p is equal to 0 to 10, preferably 0 to 2, subjected to an initial catalytic hydrosilylation reaction with a siloxane oligomer of formula: R2 (CH3) 2 SiO [(CH3) 2 SiO] s [CH3 (CH = CH2) SiO] tSi (CH3 ) 2R2, in which R2 is a vinyl group -CH = CH2 or methyl, to hang the oligomer with a vinyl group on it, but without crosslinking it, and then together with a platinum hydrosilylation catalyst, in a water-miscible solvent, it is transferred to water containing a surfactant with an emulsion produced in which microspheres are produced, crosslinking the polymer as a result of the hydration process silylation with the simultaneous production of SiOH groups, after which the hydrophilic microspheres separated from the emulsion are optionally subjected to modification by reacting them with reactive silanes with the general formulas: (CH3) m [X (CH2) n] SiY3-m and / or (CH3 ) m [CH3 (CH2) n '] SiY3-m, in which X is a functional group selected from the group consisting of amino, N-alkylamino, 1,2-NN'-ethylenediamine, diarylophosphine, halogen, thiol, epoxy, glycidoxy , methacrylic, imidazole, pyridine, oxime or isocyanate, Y is an alkoxy group, preferably methoxy or ethoxy, and when the functional group X is not basic with a halogen, most preferably chlorine, or an acyloxy group.
