Description
Известен способ радиационной прививки мономера к издели м из полимера, осуществл емый в паровой фазе.A known method of radiation grafting monomer to polymer products is carried out in the vapor phase.
Предлагаетс способ прививки мономера к издели м из полимера, осуществл емый в паровой фазе, в присутствии инициаторов радикальной 1полимеризации. Например, осуществл ют прививку стирола или метилметакрилата , наход щихс в правой фазе, к пленкам из полиэтилена, или полипропилена, или из их сополимера к волокнам из полипропилена и к гранулам из сополимера стирола и дивинилбензола в присутствии инициаторов радикальной полимеризации, например азодинитрилизомасл ной кислоты, перекиси бензоила и т. д.A method is proposed for grafting monomer to polymer products, carried out in the vapor phase in the presence of radical polymerization initiators. For example, styrene or methyl methacrylate in the right phase is grafted to films of polyethylene or polypropylene, or from their copolymer to polypropylene fibers and styrene-divinylbenzene copolymer granules, in the presence of radical polymerization initiators, for example azodyne nitrile-butyric acid, benzoyl peroxide, etc.
Привитые таким образом пленки, волокна и гранулы могут быть использованы дл различных целей, например могут подвергатьс сульфироваиию или хлорметилнрованию с последующим анинированием дл получени Films, fibers, and granules thus grafted can be used for various purposes, for example, they can be subjected to sulphurization or chloromethylation and then aninirovanie to obtain
ионИТОН.IONITON.
Ионитовые пленки, изготовленные нредлагаемым способом, отличаютс высокой прочностью (предел прочности при разрыве 65 70 кг/см), эластичностью (относительное удлинение при разрыве 40-65%), однородностью состава и строени , газонепроницаемостью и электропроводностью, близкой к электропроводности водных растворов электролитов .Ionite films made by the proposed method are distinguished by high strength (tensile strength at break 65–70 kg / cm), elasticity (elongation at break 40–65%), uniformity of composition and structure, gas impermeability and electrical conductivity close to the electrical conductivity of aqueous electrolyte solutions.
Гранулы ИОНИ10В с привитым к ним дополнительным количеством стирола после введени в них ионогенных групп, обладают на 25-45% более высокой емкостью поглощени в том же объеме по сравнению с обычно синтезируемыми ионнтами.IONI10B granules with an additional amount of styrene grafted to them after the introduction of ionogenic groups into them, have a 25-45% higher absorption capacity in the same volume as compared to the commonly synthesized ions.
При м е р. Пленка, волокно, гранулы выдерживаю в мономере, в котором предварительно был растворен инициатор. НабуханиеAn example. Film, fiber, granules stand in the monomer, in which the initiator was previously dissolved. Swelling
провод т в услови х, обеспечивающих проникГ1овение оптимального количества мономера в толщу издели . В перечисленных выше случа х набухание нроизвод т при 40-50°С в течение 20 мин. В качестве инициатора наиболее целесообразно примен ть азодинитрилозамасл ную кислоту. Количество стирола, проникающего при этих услови х в полиэтилен или в полипропилен, составл ет 20-35 вес. %, в гранулы сополимера стирола и дивинилбензола (3.% звеньев дивинилбензола) проникает 70 вес. % стирола и 25-30% метилметакрилата .conducted under conditions ensuring the penetration of the optimal amount of monomer into the thickness of the product. In the cases listed above, the swelling is produced at 40-50 ° C for 20 minutes. As the initiator, it is most expedient to use azodinitrile-butyric acid. The amount of styrene penetrating under these conditions into polyethylene or polypropylene is 20-35 wt. %, 70 weight% penetrates into styrene-divinylbenzene copolymer granules (3.% divinylbenzene units). % styrene and 25-30% methyl methacrylate.
Набухшее изделие помещают в камеру над слоем расчетиого количества мономера. Камеру нагревают до 60°С в случае прививки стирола к полипропилену, сополимеру СЭП или к гранулам сополимера стирола и дивииилбензола . Метилметакрилат прививают при 80-85°С к полипропилену или к сополимеру, 3 &ИСИМОСТИ от температуры. Привес издели достигает 40-180% и колеблетс в зависимости от количества мономера в набухшем 1зделии или от длительности выдерживани в камере. Количество гомополимера в издеЛИИ , определ емое методом экстракции, не превышает 3%. Прививку мономера к пленкам можно осуществл ть на установках непрерывного действи . 4 Предмет изобретеии Оиособ прививки моиомера к издели м из полимера, осуществл емый в паровой фазе, отличающийс тем, что, с целью получени продукта с высокой степенью прививки, процесс ведут в присутствии инициаторов радикальной полимеризации, The swollen product is placed in the chamber above the layer of the calculated amount of monomer. The chamber is heated to 60 ° C in the case of grafting of styrene to polypropylene, copolymer of EPF or to granules of copolymer of styrene and diviylbenzene. Methyl methacrylate is grafted at 80-85 ° C to polypropylene or to a copolymer, 3 & HOW from temperature. The weight gain of the product reaches 40-180% and fluctuates depending on the amount of monomer in the swelled product or on the duration of exposure in the chamber. The amount of homopolymer in the product, determined by the extraction method, does not exceed 3%. Monomer grafting to films can be carried out on continuous installations. 4 Subject of the invention: Metering of myomer to polymer products carried out in the vapor phase, characterized in that, in order to obtain a product with a high degree of grafting, the process is carried out in the presence of radical polymerization initiators,
