Известен способ .получени водорастворимых сополимеров путем взаимодействи N-ви11ил пирролидона с с ,-фенил1винилфосф,иповой кислотой в pacTiBope при xeMineipaType 50 -100° С в присутствии ди-нитрила азоизомасл ной кислоты. Получаемые сополимеры обладают повыше«ной термо- и огнестойкостью .The known method is to obtain water-soluble copolymers by reacting N-vi11yl-pyrrolidone with-phenyl 1-vinyl phosphate, ipic acid in pacTiBope at xeMineipaType 50-100 ° C in the presence of azo-isobutyric acid di-nitrile. The resulting copolymers have higher thermal and fire resistance.
С целью получени новых сополимеров, обладающих .повышенной хИМической стойкостью и комллемсообразующей опособ|Ностью предлагаетс в качестве сомоно меров а-фенилвИНилфосфиновой кислоты использовать амиды а.криловой или метакрилавой кислот.In order to obtain new copolymers possessing increased chemical resistance and complexing agent, Nostie proposes to use amides of acrylic acid or methacrylate acid as co-monomers of a-phenylvinyl-vinylphosphinic acid.

Получаемые соеолимеры можно использовать в качестве термостойких и химически СТОЙ1КИХ веществ, а также как ко.мплексообразующие и экстрагирующие .полимерные агенты и водорастворимые полизлектролиты дл осветлени промышленных растворов.The resulting co-polymers can be used as heat-resistant and chemically resistant substances, as well as complex-forming and extracting polymeric agents and water-soluble poly-electrolytes to clarify industrial solutions.
Сополимеры легко растворимы в воде и органи1Чбаких растворител х и в отличие от сополимеров, полученных известным способом, их растворы не кетоенолизируют.The copolymers are readily soluble in water and organic solvents and, unlike copolymers prepared in a known manner, their solutions are not ketoenolized.

Solimerization of a-phenyl vinylphosphinic acid (cc-PVC; t. C) with acrylamide (or methacrylamide) LDH of different molomeroib ratios in the initial mixture is carried out in a different aiM-5 pool in a nitrogen atmosphere or treated with azo- nitrile isomeric acid; the total weight of the model: s) prn 80 ° C in the environment of the dnixal. The ratio of the total weight of monomers to the weight of the solvent is 1: 1. The copolymerisation time depends on the ratio of the initial camotants (see table). Purified copolymers are alalized. 4 P-re d.me. of the invention for creeping water-soluble soiolimers by reacting a-phenylvinylfoil / sphylic acid with vinylamide upon heating in solution IB and dissolving dioitrile of azo-butyric acid, characterized in that, with the production of hearth. chemical resistance and complexing ability, as the vinyl 1Mide use amide of acrylic or methacrylic acid.
