Scientists develop non-stick chewing gum

LONDON (Reuters) - Scientists have developed a non-stick
chewing gum that can be easily removed from pavements, shoes
and clothes.The new gum, the result of polymer research at the
University of Bristol, could be launched commercially in 2008,
its backers said on Friday.
"The advantage of our Clean Gum is that it has a great
taste, it is easy to remove and has the potential to be
environmentally degradable," said Terence Cosgrove, a professor
of chemistry who helped found a company called Revolymer to
commercialise the technology.
Today's chewing gums are made from synthetic latex, which
is resistant to the weather and is strongly adhesive. The new
gum adds a special polymer to modify its properties, making it
far less sticky.
In two street trials, leading commercial gums remained
stuck to the pavement three out or four times, while Clean Gum
came away naturally within 24 hours in all cases, Revolymer
said..
