Polyisoprene is strictly speaking a collective name for polymers that are produced by polymerization of isoprene. In practice polyisoprene is commonly used to refer to synthetic cis -1,4-polyisoprene, made by the industrial polymerisation of isoprene.

聚异戊二烯（POLYISOPRENE），是异戊二烯 （2－ 甲基 -1，3- 丁二烯）的聚合物，英文缩写为PI。 有4种立构规整结构：其中1，2和3，4结构又各有全同和间同两种 立体异构体。 工业上重要的是顺-1，4-聚异戊二烯，又称“ 天然乳胶 ”，于1958年被发现。 英文缩写为PI。 它有4种立构规整结构： 其中1，2和3，4结构又各有全同和间同两种 立体异构体。 自然界只存在两种异构体，即顺-1，4-聚异戊二烯（天然橡胶，三叶胶）和反-1，4-聚异戊二烯（杜仲胶， 古塔波胶）。 共有两 …

Polyisoprene is made by solution polymerization of isoprene (2-methyl-l,3-butadiene). The isoprene monomer, the structural unit of the natural rubber polymer, can polymerize in four isomeric forms: trans 1,4 addition, cis 1,4 addition, 1,2 addition, leaving a pendant vinyl group, and 3,4 addition.

2025年2月9日 · polyisoprene, polymer of isoprene (C 5 H 8) that is the primary chemical constituent of natural rubber, of the naturally occurring resins balata and gutta-percha, and of the synthetic equivalents of these materials.

Polyisoprenoids are one of the eight major classes of biopolymers produced by living organisms (Linos and Steinbüchel, 2005). Together with cellulose, lignin and starch, natural rubber (NR) (one representative of polyisoprenoids) is one of the most widely used biopolymers.

Polyisoprene is a crucial synthetic polymer, renowned for its versatile attributes. It closely mimics natural rubber’s characteristics due to its similar polymer structure, rendering it an invaluable player in various industrial applications.

Polyisoprenes are bio-based synthetic rubbers that are produced by polymerizing isoprene recovered from cell culture medium. They are commonly used in manufacturing tires and various other applications.

Polyisoprene...is a homopolymer of isoprene (2-methyl-1,3-butadiene)... Polyisoprenes have a polymer structure similar to that of natural rubber.

Lithium-dependent initiators are unique compared with other alkali metals since they can produce polyisoprenes containing 1,2-, 3,4-, and trans-1,4-polyisoprene. It is remarkable how important the role of the solvent is for the polymer structure in the polymerization process.
