Benefits of technology

The technical effect of this patented method involves creating uniformly colored particles from an emulsion containing both vinyl benzyl alcohol-styrene monomer ("BSM") and divinylenebenzyme A ("DPM"). These particles can be used alone or mixed together into products that have improved properties such as increased resistance against breakage during use compared to existing methods without these particles. This results in longer lifespan and reduced energy usage than traditional methods due to less expensive starting material being added instead of adding more chemical agents like BSM' s crosslinkers.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of ion-exchange resin used for separating soluble materials from liquids without losing their effectiveness over time due to its weaknesses such as high breakdown voltage and limited lifetimes caused by impurities present during production process.

Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 . The "seed" component (parts by weight) used for the preparation of styrene copolymerized homogeneous resin: at least 100 styrene, 0.1 divinylbenzene, 0.35 initiator, 110 deionized water, 0.8 dispersant, and 0.10 sodium salt. Add deionized water, dispersant, and sodium salt into the polymerization reactor and stir, and then put the initiator, divinylbenzene, and styrene into the reactor and stir evenly. After the closed reactor is ventilated with nitrogen to remove the air in the reactor, the temperature is raised to react. The reaction temperature is controlled within the range of 60-110°C (best 80-90°C), and the reaction time is 18-25 hours (best 20-22 hours). Sift the seeds.

Embodiment 2

[0011] Embodiment 2: with reference to attached figure 1 . The "seed" component (parts by weight) used for the preparation of styrene copolymerized homogeneous resin: at least 100 styrene, 0.35 divinylbenzene, 0.10 initiator, 250 deionized water, 0.3 dispersant, and 0.30 sodium salt. Add deionized water, dispersant, and sodium salt into the polymerization reactor, stir at the same time, then put the initiator, divinylbenzene, and styrene into the reactor and stir evenly, and then seal the reactor with nitrogen to remove the air in the reactor, then heat up Reaction, the reaction temperature is controlled within the range of 60-110°C (best 80-90°C), the reaction time is 18-25 hours (best 20-22 hours), and after the reaction is completed, the material is cooled below 40°C and discharged, washed with water, Dry and sieve the seeds.

Embodiment 3

[0012] Embodiment 3: with reference to attached figure 1 . The "seed" component (parts by weight) used for the preparation of styrene copolymerized homogeneous resin: at least 100 styrene, 0.225 divinylbenzene, 0.225 initiator, 180 deionized water, 0.55 dispersant, and 0.20 sodium salt. Add deionized water, dispersant, and sodium salt into the polymerization reactor, stir at the same time, then put the initiator, divinylbenzene, and styrene into the reactor and stir evenly, and then seal the reactor with nitrogen to remove the air in the reactor, then heat up Reaction, the reaction temperature is controlled within the range of 60-110°C (best 80-90°C), the reaction time is 18-25 hours (best 20-22 hours), and after the reaction is completed, the material is cooled below 40°C and discharged, washed with water, Dry and sieve the seeds.

Abstract

A styrene-series ion exchange resin (homogeneous styrene copolymerized resin) is prepared through under existance of styrene trigger polymerizing to obtain "seeds", and suspension copolymerizing reaction between said seeds, styrene and divinyl benzene in water-phase medium under the action of trigger. Its advantages are high strength and exchange performance, long service life, and high output rate.
