Abstract

Wynalazek ujawnia fotochromowe kopolimery azobenzenowe o wzorze ogólnym 1, będące poli(2-metyloprop-2-enianem 4-[(E)-(4-hydroksyfenylo)diazenylo]-N -(5-metyloizoksazol-3-ilo)benzeno-sulfonoamidu), w którym n oznacza liczbę merów od 1 do 50. Homopolimery znajdują zastosowanie w optycznym zapisie i przetwarzaniu informacji, a także do wytwarzania mikroobiektów i nanoobiektów takich jak: mikrosfery, nanosfery, mikropręty, nanopręty, mikrodruty, nanodruty, mikrowłókna i nanowłókna. Wynalazek obejmuje także sposób wytwarzania fotochromowych homopolimerów azobenzenowych o wzorze 1, polegający na tym, że 2-metyloprop-2-enian 4-[(E)-(4-hydroksyfenylo)diazenylo]-N -(5-metyloizoksazol-3-ilo)benzeno-sulfonoamidu rozpuszcza się w mieszaninie tetrahydrofuranu, ?-butyrolaktonu i N,N-dimetyloformamidu o zawartości 58% objętościowych tetrahydrofuranu i 17% objętościowych N,N-dimetyloformamidu i poddaje polimeryzacji rodnikowej w obecności inicjatora w postaci nadtleneku dibenzoilu, w atmosferze gazu inertnego takiego jak azot lub argon, w temperaturze od 70 do 100°C.The invention discloses photochromic azobenzene copolymers of general formula 1, which are 4 - [(E) - (4-hydroxyphenyl) diazenyl] -N - (5-methylisoxazol-3-yl) benzene sulfonamide poly (2-methylprop-2-enoate) of general formula 1 , in which n is the number of units from 1 to 50. Homopolymers are used in the optical recording and processing of information, as well as for the production of micro objects and nano objects such as: microspheres, nanospheres, microspheres, nanowires, microducts, nanowires, microfibers and nanofibers. The invention also includes a method for preparing photochromic azobenzene homopolymers of formula 1, in which 4 - [(E) - (4-hydroxyphenyl) diazenyl] -N - (5-methylisoxazol-3-yl) 2-methylprop-2-enate benzene sulfonamide is dissolved in a mixture of tetrahydrofuran, β-butrolactone and N, N-dimethylformamide with 58% by volume tetrahydrofuran and 17% by volume N, N-dimethylformamide and subjected to radical polymerization in the presence of a dibenzoyl peroxide initiator in such an inert gas atmosphere like nitrogen or argon, at 70 to 100 ° C.
