Abstract

Wynalazek ujawnia fotochromowe kopolimery metakrylanu butylu będące fotochromowym kopolimerem azobenzenowym metakrylanu butylu z 2-Tmetyloprop-2-enianem, 4-[(E)-(4-hydroksyfenylo)diazenylo]-N -(5-metyloizoksazol-3-ilo)benzeno-sulfonoamidu o wzorze 1, w którym n oznacza liczbę merów od 1 do 50 2-metyloprop-2-enianu 4-[(E)-(4-hydroksyfenylo)diazenylo]-N -(5-metyloizoksazol-3-ilo)benzeno-sulfonoamidu, natomiast y oznacza liczbę merów od 1 do 50 metakrylanu butylu- znajdujące 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 ujawnia również sposób wytwarzania fotochromowych kopolimerów metakrylanu butylu będących fotochromowym kopolimerem azobenzenowym metakrylanu butylu z 2-metyloprop-2-enianem 4-[(E)-(4-hydroksyfenylo)diazenylo]-N -(5-metyloizoksazol-3-ilo)benzeno-sulfonoamidu o wzorze 1. Sposób charakteryzuje się tym, że metakrylan butylu w stosunku molowym 1:1 rozpuszcza się w mieszaninie tetrahydrofuranu, ?-butyrolaktonu i N,N-dimetyloformamidu o zawartości 58% objętościowych tetrahydrofuranu i 17% objętościowych N,N-dimetyloformamidu i poddaje się polimeryzacji rodnikowej w obecności inicjatora w postaci nadtlenku dibenzoilu, przy czym reakcję prowadzi się w atmosferze gazu inertnego, w temperaturze od 70 do 100°C.The invention discloses photochromic butyl methacrylate copolymers which are a photochromic copolymer of butyl methacrylate azobenzene with 2-T-methylprop-2-enate, 4 - [(E) - (4-hydroxyphenyl) diazenyl] -N - (5-methylisoxazol-3-yl) benzene sulfonamide of formula 1 in which n is the number of units from 1 to 50 4 - [(E) - (4-hydroxyphenyl) diazenyl] -N - (5-methylisoxazol-3-yl) benzene sulfonamide 2-methylprop-2-enoate , while y is the number of units from 1 to 50 butyl methacrylate - 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 discloses a method for producing photochromic butyl methacrylate copolymers which are a photochromic butyl methacrylate copolymer with 4 - [(E) - (4-hydroxyphenyl) diazenyl] -N - (5-methylisoxazol-3-yl) benzene 2-methylprop-2-enoate. -sulfonamide of formula 1. The method is characterized in that butyl methacrylate in a 1: 1 molar ratio 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 an initiator in the form of dibenzoyl peroxide, the reaction being carried out in an inert gas atmosphere at a temperature of 70 to 100 ° C.
