Annual lecture delivered at VRC
Right from toothbrush to pen, bucket and mosquito nets many things are made up of polymers. Hence it is very difficult to imagine the life without their use, as they have become an integral part of our day-to-do activities, according to Prof A. Varada Rajulu of polymer science department of Sri Krishnadevaraya University of Anantapur.
Delivering the 14th S. Ananda Ramammurthy (SAR) memorial annual lecture at V. R. College Nellore the professor spoke at length on application of polymers and their physical properties. “The first-ever polymer material prepared was cellulose nitrate extracted from cotton in 1859.”
And the use of polymers had significantly gone up during the Second World War.
At present reinforced polymers, polymer composites and blends are being developed and used extensively in the fields of transport, sports, space applications and domestic purposes.
Therefore there is an urgent need to adopt safety measures in a bid to control the pollution being caused by the use of polymers.
Local MLA as well as secretary and correspondent of V. R. College committee Anam Vivekananda Reddy inaugurated the programme while it was presided over by college principal V. R. Ramachandra Reddy.
Head of the physics department Dr. A. Sundar Jacob welcomed the gathering. Two final year B. Sc (M.P.C) students - B. V. L. Krishna Priya and M. Kejiyamma were presented S. A. R memorial scholarships and certificates.
