The first rubber plant in Europe SK-1 (from Russian "Synthetic Kauchuk", Russian: ??-1) was established (Russia) by Sergei Lebedev in Yaroslavl under Joseph Stalin's first five-year plan on July 7, 1932.
In 1935, German chemists synthesized the first of a series of synthetic rubbers known as Buna rubbers. These were copolymers, meaning the polymers were made up from two monomers in alternating sequence. Other brands included Koroseal, which Waldo Semon developed in 1935, and Sovprene, which Russian researchers created in 1940

Place one synthetic rubber plants and marker in the HOME territory of your choice. Germany receives 1 marker for the plant each turn.
Place one synthetic rubber plants and marker in the HOME territory of your choice. UK receives 1 marker for the plant each turn.
USA - 1941
Place two synthetic rubber plants and markers in the HOME territory of your choice. From 1940 on, USA will receive 2 markers for every plant representing Americans reliance on synthetic rubber in the early 1940’s.
Do to an abundance of natural rubber captured by the Japanese in their conquests of the South Pacific, Japans use on synthetic rubber was not that great.
Use: Each 2 markers allows you reduce the cost of ONE air or ONE motorized unit by 1 IPP representing the use of synthetic rubber in those units. You must use 2 Markers together when you have two together and no stockpiling of more than 2 markers at a time. You can stockpile one only.
