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.

About 95% of isoprene production is used to produce cis-1,4-polyisoprene—a synthetic version of natural rubber. [ 14 ] Natural rubber consists mainly of poly-cis-isoprene with a molecular mass of 100,000 to 1,000,000 g/mol. Typically natural rubber contains a few percent of other materials, such as proteins, fatty acids, resins, and inorganic ...
Chemical structure of cis-polyisoprene, the main constituent of natural rubber. Synthetic cis-polyisoprene and natural cis-polyisoprene are derived from distinct precursors, isopentenyl pyrophosphate and isoprene. Rubber is the polymer cis-1,4-polyisoprene – with a molecular weight of 100,000 to 1,000,000 daltons.
Isoprene is a natural monomer that polymerizes to form a natural rubber, most often cis-1,4-polyisoprene, but also trans-1,4-polymer. Synthetic rubbers are often based on butadiene , which is structurally related to isoprene.
A major manifestation of creative synthesis is the concept of heterogony of ends. Heterogony of ends is the development of new motives during the series of events. [ 6 ] There is an exchange of motives in our immediate experience and it defines the social behaviors that are engaged in as well as, the cognitive reaction to the world that occurs.
Psychosynthesis is a framework and approach to psychology developed by Italian psychiatrist Roberto Assagioli. It is "one of the prime forces in transpersonal psychology." It "stretches beyond the boundaries of personal psychology and individuality by postulating a deeper center of identity: the Self, our essential Being.
Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry , analytical ...
