Conventional polyolefin-based thermoplastic elastomers have a variety of merit. But the copolymers including block, graft and blend types have some limitations due to their low use temperature. In this study, novel polyolefin-g-poly(t-butylstyrene) as one of the promising high utility temperature polyolefin-based thermoplastic elastomers was synthesized by the graft anionic living polymerization from the initiation of styrene unit form the poly(t-butylstyrene) hard grafts along the poly(ethylene-ter-1-hexane-ter-divinylbenzene) backbone as the soft block (0.3~0.5 mol% of graft sites). Phase-separation occurred in these polyolefin TPEs when the Mn of poly(t-butylstyrene) was more than 5,000 g/mol, which was evidenced by the presence of two distinct Tgs(-20°C of polyolefin soft block and 125°C of poly(t-butylstyrene) hard block) observed in DSC and DMTA. These high temperature polyolefin TEPs exhibited distinct mechanical property with high modulus and toughness even above 125°C. And when the content of P(t-butylstyrene) over 28wt%, excellent mechanical properties: high tensile strength (>21MPa) with high elongation (>1,100%) could be obtained, similar to that of S-EB-S(30wt% styrene content). The multi-carboxyl functionalized polyolefin-g-poly (t-butylstyrene) could be synthesized by the incorporation of high vinyl oligo-isoprene at the end of poly (t-butylstyrene) hard block via sequential anionic polymerization followed by the thiolene click reaction with thioglycolic acid to incorporate multi-carboxyl groups at the pendant vinyl units. The contact angle of these result multi-carboxyl functionalized polyolefin (12-COOH/molecule) was decreased to 58° compared to 95° in case of the non-functionalized polyolefin TPEs.

Petroleum products play an important role in economic development of any nation. At present oil producing sector takes a leading position in the structure of national economy of Kazakhstan. Kazakhstan's oil producing sector is quickly developing. Crude oil production grew from 40 in 2001 to 80 million tons in 2015 i.e. for 2 times. The oil and gas basins of Kazakhstan can be grouped into four revealed or prospective oil and gas provinces in the Republic of Kazakhstan. They are: 1. The Pre-Caspian Basin lies in the western part of the country, behind the Mugodzhary Mountains. The geology of this province is made up of Paleozoic sediments covering a Proterozoic basement. 2. The Mangistau-Usturt Basin lies in the Mangistau and Aqtobe areas of Kazakhstan. 3. The Central Kazakhstan Basin lies in the eastern and southern areas of Kazakhstan. 4. The Western Siberian Basin is in the northern and northeastern region of Kazakhstan, north of the Kokshetau Mountains. The geology is of a platform type, with a Mesozoic cover overlying a Paleozoic basement. Also, in the territory of Kazakhstan discovered huge amount of oil sands, which accumulated in over 50 fields. Its reserve is more than conventional oil of Republic. These oil sands resources are called unconventional oil to distinguish them from oil which can be extracted using traditional oil well methods. Oil sands situated in Western part of Kazakhstan, such as Aqtobe, Atyrau and Mangistau regions.
