| titleOfInvention | The method that inverse suspension polymerization prepares acrylamide polymer microballoon |
| abstract | The present invention relates to a kind of method that inverse suspension polymerization prepares acrylamide polymer microballoon, the problem of preparation system is unstable, the easy aquation of microballoon heat ageing is decomposed present in prior art is mainly solved.The present invention is by terms of parts by weight, 0.01~10 part of dispersant is dissolved in 30~90 parts of decentralized media, under stirring, add the crosslinking agent for containing 0.001~2 part for being adjusted to neutrality, 1~50 part of the first monomer, 10~70 parts of water of 0.0001~50 part of second comonomer and/or 0.0001~50 part of Third monomer, obtain dispersion, it is heated to 25 80 DEG C under an inert atmosphere again, the initiator of 0.0001~5 part of addition, carry out inverse suspension polymerization, reaction obtains the technical scheme of acrylamide polymer microballoon for 0.5~8 hour, preferably solve the problem, it can be applied in tertiary oil production in oil field make water plugging profile control agent to improve oil recovery factor. |
