Synthomer

Synthomer plc (), formerly known as Yule Catto & Co, is a British-based chemicals business. It is a constituent of the FTSE 250 Index.
History.
The company traces its roots back to 1863, when Andrew Yule founded a trading house known as "Andrew Yule & Co." in Calcutta. At the same time Andrew's brother, George Yule, set up "George Yule & Co." in London, which acted as British agency arm of Andrew Yule & Co.
When in 1919 Andrew Yule & Co. and George Yule & Co. were sold to the US banking group J.P. Morgan & Co. and its British merchant banking affiliate Morgan Grenfell & Co., both were turned from a partnership into a private limited company. That same year Thomas Catto (1879–1959) was sent to India to take over the management of the firm from Sir David Yule (1858–1928), a nephew of Andrew Yule. David Yule continued to hold the title of Chairman but had no active part in the operations of the business.
In 1920 Thomas Catto and David Yule changed the name of the British purchasing arm of Andrew Yule & Co., George Yule and Company, to "Yule, Catto & Company Ltd." Due to increased taxation, the devaluation of the Indian rupee and the abolition of the managing agency system, Yule, Catto & Co decided in 1969 to sell its shareholding in Andrew Yule & Co. to the Indian government.
With the acquisition of "Revertex Chemicals" in 1980, Thomas Catto's son, Stephen (1923–2001) started to turn Yule Catto & Co. into an international speciality chemicals and building products manufacturer. Since 2007 the group has been transformed from a diversified chemical business to a focussed speciality polymer business. In 2012 the company changed its name to Synthomer on the basis that the majority of its business already traded under that name.
In July 2019, Synthomer announced that it was going to buy OMNOVA Solutions for an enterprise value of $824 million; the transaction was completed on 2 April 2020.
Operations.
The company has three activities: polymer chemicals, pharma chemicals and impact chemicals.
