The present disclosure relates to a process for preparing of high thermal conductivity and high heat capacity oriented ultrahigh molecular weight polyethylene (UHMWPE) product. The process includes feeding UHMWPE through rollers to obtain a pre-laminate which is further hot stretched to obtain the oriented UHMWPE product having high thermal conductivity and high heat capacity. The temperature of stretching is maintained below the melt temperature of the UHMWPE throughout the entire process. There is also provided a high thermal conductivity and high heat capacity oriented UHMWPE product prepared by the process of the present disclosure. The oriented UHMWPE product is characterized in the axial thermal conductivity in the range of 70 to 200 W/mK, transverse direction thermal conductivity in the range of 0.022 to 0.045 W/mK and heat capacity in the range of 6 to 25 MJ/mK.

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.
