Polybutadiene [butadiene rubber, BR] is a synthetic rubber. It offers high elasticity, high resistance to wear, good strength even without fillers, and excellent abrasion resistance when filled and vulcanized. "Polybutadiene" is a collective name for homopolymers formed from the polymerization of the monomer 1,3-butadiene.
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.
The Arabic spoken in Indonesia is generally used by people of Arabs descent and Islamic students (santri), primarily based on Hadhrami Arabic brought by Arab traders from Hadramaut, Yemen. This language has a unique feature, which is the mixture of vocabulary from Arabic and Indonesian, as well as other regional languages.
2 CH 3 CH 2 OH → CH 2 =CH−CH=CH 2 + 2 H 2 O + H 2. This process was the basis for the Soviet Union's synthetic rubber industry during and after World War II, and it remained in limited use in Russia and other parts of eastern Europe until the end of the 1970s. At the same time this type of manufacture was canceled in Brazil.
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. The presence of isomers other than ...
This list of Arab Indonesians includes names of figures from ethnic Arab descent, especially Hadhrami people, in Indonesia.This list also includes the names of figures who are genetically of Arab blood, both those born in the Arab World who later migrated to Indonesia (), or who were born in Indonesia with Arab-blooded parents or Arab Indonesians mix ().
1,2-Butadiene is the organic compound with the formula CH 2 =C=CHCH 3. It is an isomer of 1,3- butadiene , a common monomer used to make synthetic rubber. It is a colorless flammable gas, one of the simplest substituted allenes .
