Description
Известны способы получени сополимеров акрилонитрила и л-диметиламиностирола . Известно также применение при этом азодинитрила изомасл ной кислоты в качестве инициатора и лаурилмеркаптана в качестве регул тора полимеризации .Methods are known for the preparation of copolymers of acrylonitrile and l-dimethylaminostyrene. It is also known to use azodinitrile isobutyric acid as an initiator and lauryl mercaptan as a polymerization regulator.
Предлагаетс способ получени волокнообразующих сополимеров на основе акрилонитрила и «-аминостирола (в соотношении от 90: 10 до 70 : 30) в присутствии азодинитрила изомасл ной кислоты в качестве инициатора и лаурилмеркаптана в качестве регул тора полимеризации .A method is proposed for preparing fiber-forming copolymers based on acrylonitrile and α-aminostyrene (in a ratio of from 90: 10 to 70: 30) in the presence of azodinitrile isobutyric acid as an initiator and lauryl mercaptan as a polymerization regulator.
Полученные из сополимера волокна приобретают способность накрашиватьс .The fibers obtained from the copolymer acquire the ability to be colored.
Пример 1. Сополимеризаци проводитс в токе азота при соотношении мономеров акрилонитрила к га-аминостиролу 90: 10. Соотношение фаз мономера к воде 1 : 5. Азодинитрила изомасл ной кислоты берут 0,5%, лаурилмеркаптаиа - 0,2Vo и эмульгатора - 5% от веса мономеров. Сополимеризаци проводитс при температуре 60° в течение 3 час.Example 1. The copolymerization is carried out in a stream of nitrogen with a ratio of acrylonitrile monomers to haminosthenol 90: 10. The ratio of monomer to water phases is 1: 5. Azodinitrile isobutyric acid takes 0.5%, laurylmercaptae is 0.2Vo and emulsifier is 5% of monomer weights. The copolymerization is carried out at a temperature of 60 ° for 3 hours.
Выход сополимера при этих услови х составит 45%. Удельна в зкость 0,5%-ного раствора в диметилформамиде - 0,762.The copolymer yield under these conditions will be 45%. The specific viscosity of a 0.5% solution in dimethylformamide is 0.762.
Полученные пленки из 17%-ного раствора сополимера в диметилформамиде хорошо окрашиваютс кислотными красител ми.The films obtained from a 17% copolymer solution in dimethylformamide are well colored with acid dyes.
Пример 2. Соотношение мономеров акрилонитрила к п-аминостиролу 80:20. Услови сополимеризации те же, что в примере 1.Example 2. The ratio of monomers of Acrylonitrile to p-aminostyrene 80:20. The copolymerization conditions are the same as in example 1.
Выход сополимера составил 31%, Удельна в зкость О.Э/о-ного раствора в диметилформамиде- 1,1.The copolymer yield was 31%. The specific viscosity of OE / th solution in dimethylformamide is 1.1.
Пример 3. Соотношение мономеров акрилонитрила к tt-аминостиролу 70:30. Услови сополимеризации те же, что в примере 1.Example 3. The ratio of monomers of Acrylonitrile to tt-aminostyrene 70:30. The copolymerization conditions are the same as in example 1.
Выход сополимера составит 50%. Удельна в зкость 0,5 /о-ного раствора в диметилформамиде - 1,03.The output of the copolymer will be 50%. The specific viscosity of a 0.5 / o-th solution in dimethylformamide is 1.03.
