天元航材是一家生產(chǎn)銷售端羥基聚丁二烯（HTPB、Hydroxyl-terminated polybutadiene）等化工原材料的廠家，其中端羥基聚丁二烯的英文名稱為Hydroxyl-terminated polybutadiene，端羥基聚丁二烯是一種液體遙爪聚合物，是一種新型液體橡膠。那么您足夠了解Hydroxyl-terminated polybutadiene嗎？今天小編給大家介紹一下吧！

Hydroxyl-terminated polybutadiene

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 properties vary because HTPB is a mixture rather than a pure compound, and it is manufactured to meet customers' specific requirements. A typical HTPB is R-45HTLO. This product consists of oligomeric units typically containing 40–50 butadiene molecules bonded together, with each end of the chain terminated with a hydroxyl [OH] group.

R-45HTLO has a functionality of 2.4-2.6, which means that there is (approximately) one additional hydroxyl group located along the chain for every two oligomeric units. This provides side-to-side linkage for a stronger cured product. HTPB is usually cured by an addition reaction with di- or poly-isocyanate compounds.
