\subsection{DF7}
Polymers are long chained molecules made from monomers. Plastics are modified polymers.
\subsubsection{Polythene}
\begin{itemize}
\item Polythere discovered by mistake due to leaky apparatus
\item Reaction had to be controlled to prevent explosion
\item Oxygen crucial - had to be perfect amount
\item Polythene has many good properties
\begin{itemize}
\item Tough
\item Durable
\item Insulating
\end{itemize}
\end{itemize}
\subsubsection{Elastomers, Plastics and Fibres}
Elastomers are soft and springy, returning to their original shape once deformed. These are in plastics.\\
Stronger polymers will not deform easily, and can be made into strong, thin fibres; nylons.\\
