Scientists have developed a non-stick chewing gum(口香糖). The new gum can 小题1: (remove) easily from pavements, shoes and clothes. It’s the result of polymer (聚合体) research at the University of Bristol and could be launched commercially in 2008. 小题2: it catches on(流行), the product will solve 小题3: major headache for present authorities around the world.
“A great 小题4: (disadvantage) of our Clean Gum is that it is easy to remove and has the potential to be 小题5: (environment) degradable (可降解的),” said Terence Cosgrove, a professor of chemistry 小题6: helped to found a company called Revolymer to commercialize the technology.
Today’s chewing gums are made 小题7:synthetic latex(人工制造的乳液), which is resistant to the weather and is strongly sticky. The new gum adds a special polymer to change its properties(特性), 小题8: (make) it far less sticky.
In two street trials, 小题9: commercial gums remained stuck to the pavement 小题10: Clean Gum came away naturally in all cases.
