WebThe properties of a polymer also depend on the reaction conditions in which the polymer was created.This includes the temperature and pressure of the reaction. Polymers can be low or high density. We can produce low density or high density polymers from a monomer. These differences are due to the conditions of the polymerisation reaction.

WebPolymers can also be shaped, once hot, by press moulding and drape forming - methods often used to shape acrylic. Once the acrylic is hot and malleable, it can be pressed over a former to take a new shape. Since polymers have a relatively low melting point, they can be shaped easily once molten by either injection moulding or extrusion. WebSlime is sometimes described as a reversible cross-linking gel. The cross-linking between the polymer chains of polyvinyl alcohol occurs by adding borax, Na 2 B 4 O 7.10H 2 O (sodium tetraborate). PVA glue contains, amongst other things, the polymer polyvinyl alcohol (also called polyethenol). Polyvinyl alcohol has the structure: fenix 7x beta firmwareWebA polymer is a substance of high average relative formula mass, made up of small repeating units called monomers.
