Abstract: Water absorbent polymers and a process for their preparation are disclosed. The process for preparing water absorbent polymers comprises preparing a slurry with relatively high amounts of polymer particles (in the range of 40 to 55 wt % of the total mass of the slurry) having water absorbed therein. The slurry is then directly spray dried to obtain water absorbent polymers.

Abstract: The present disclosure relates to the field of rubbers. The halogenated isobutylene isoprene rubber is prepared by polymerizing isoprene monomer and isobutylene monomer, followed by halogenation using a halogenating agent. This process of the present disclosure is simple, energy efficient and economic.

Abstract: The present disclosure relates to a process for the preparation of CPVC which includes reacting PVC with chlorine at a pre-determined temperature in the presence of at least one irradiation source having wavelength ranging from 254 and 530 nm while maintaining the radiant flux from 1.5 to 2 W/kg of PVC, irradiance at 0.13 W/cm2 and the number of photons emitted per second from 3×1018 to 5×1018, under agitation, for a time period ranging from 3 to 4 hours to obtain CPVC. The CPVC prepared from the afore-stated process has a whiteness index ranging from 89 to 96, a yellowness index ranging from 1.23 to 1.73 and stability ranging from 648 to 684 seconds. The rate of the chlorination reaction after employing the afore-stated process parameters ranges from 1.6 to 4.36 mole/hour/kg.
