- 1ADDING CROSSLINKS-cross links hold the polymer chain in a fixed position
-strong force of attraction between chains
-high melting point
-rigid, hard and strong - 2DECREASING CHAIN LENGTH-weak, soft and low melting point
-shorter chains can be easily separated
-weak forces of attraction between chains - 3ADDING PLASTICISERS-flexible, soft and low melting point
-plasticisers act like oil between the chains making them slip and slide
-weak forces of attraction between the chains - 4DECREASING CRYSTALLINITY-flexible, weak and low melting point
-the side branches prevent the polymer chains packing closely together - 5INCREASING CHAIN LENGTH-strong, hard and high melting point
-longer chains can pack closely together and can also get tangled
-strong forces of attraction between polymer chains - 6—
