    I just read the chemistry pre-release which is on polymers and how fuel prices are rising so there is need to replace heavy metals etc. with lighter polymers to be used in transport vehicles.
    It talks about acrylic adhesives and how there are new developments which has meant that they can be used with poly(ethene) and poly(propene) as effective adhesives.

    Could you please give me any useful info about this and questions which could come up??

    Thanks!

    apparently we should draw out the molecular formula and structural formulas for the substances e.g nylon given in the table on the first page
