Four clear powerpoint slides that show crystallinity in HDPE, random chains in LDPE, thermosetting polymers and thermosoftening polymers.
I go through it using the IWB but print out the slides, two on a paged,backed, without the diagrams, to give pupils the opportunity to draw out the different structures.
Something went wrong, please try again later.
All the information in 4 slides with diagrams - thanks for sharing
