1,3-Butadiene is an organic compound that is a simple conjugated diene hydrocarbon (dienes have two carbon-carbon double bonds). Polybutadiene forms by linking many 1,3-butadiene monomers to make a much longer polymer chain molecule.
Hydroxyl-terminated polybutadiene (HTPB) is an oligomer of butadiene terminated at each end with a hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers. HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup.
Polybutene is an organic polymer made from a mixture of 1-butene, 2-butene, and isobutylene.Ethylene steam cracker C4s are also used as supplemental feed for polybutene. It is similar to polyisobutylene (PIB), which is produced from essentially pure isobutylene made in a C4 complex of a major refinery.
Indonesian Arabic (Arabic: العربية الاندونيسية, romanized: al-‘Arabiyya al-Indūnīsiyya, Indonesian: Bahasa Arab Indonesia) is a variety of Arabic spoken in Indonesia. It is primarily spoken by people of Arab descents and by students ( santri ) who study Arabic at Islamic educational institutions or pesantren .

PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid.PBAT is produced by many different manufacturers and may be known by the brand names ecoflex, Wango, Ecoworld, Eastar Bio, and Origo-Bi.
Crystallization from solution yields form-III with the melting point of 106.5 °C. Cooling from the melt results in the form II which has melting point of 124 °C and density of 0.89 g/cm 3 . At room temperature, it spontaneously converts into the form-I with the melting point of 135 °C and density of 0.95 g/cm 3 .
