Common Mistakes When Using “polyisoprene”

- Using it interchangeably with 'rubber' in non-technical writing, which will confuse general readers.
FAQ
Frequently Asked Questions
Natural rubber is *a* polyisoprene (specifically, cis-1,4-polyisoprene). However, 'polyisoprene' often refers to the synthetic version, and 'rubber' can refer to many other elastomers. They are not perfectly synonymous.
It is used to make products requiring high purity and elasticity without latex allergens, such as surgical gloves, bottle nipples, adhesives, and specialised seals.
It is classified as an elastomer, a type of rubber. While all rubbers are polymers, they are distinct from common rigid or semi-rigid plastics.
In British English: /ˌpɒl.iˈaɪ.səʊ.priːn/ (pol-ee-EYE-soh-preen). In American English: /ˌpɑː.liˈaɪ.soʊ.priːn/ (pah-lee-EYE-soh-preen). The primary stress is on the 'eye' syllable.
A polymer of isoprene, which is the primary chemical constituent of natural rubber.
Polyisoprene is usually specialised scientific / industrial technical in register.

Memory Aids
Mnemonic
Think: 'POLYmer' of 'ISOPRENE'. Many (poly) isoprene molecules linked together make this rubbery material.
