Monomers join together to form long chains of repeating units called polymers via a process known as polymerization.
However, propane, as a monomer, will not polymerize without modifying it in some way to make it more reactive. The closest approximation is polyethylene, made up of repeating two carbon ethyl groups, giving a continuous strand of CH2 units, which would be the theoretical result of polypropane.
Of course, there's polypropylene, which is methyl polyethylene. It's not a straight chain of carbons, but rather has a methyl group attached to every other methylene group.

I think you meant propene, didn't you ? Because propane molecules, being saturated, will not react together to form anything. When propene molecules react together to form long chains, the product is polypropylene and the reaction is polymerisation - specifically, addition polymerisation.

Chemically, polypropylene interior of reason inert. although, it particularly is going to react with chlorine, with the chlorine atoms changing the hydrogen atoms interior the polymer chain. Fluorine will react further, however the reaction is amazingly violent and particularly exothermic. Polypropylene will additionally burn in oxygen if heated: (CH2CH(CH3))n + 4·5n O2 ---> 3n CO2 + 3n H2O Its actual properties count at one in all those polypropylene you're speaking approximately. actual, there are 3 types: syndiotactic (wherein all the methyl facet-chains are all on an identical facet of the main chain), isotactic (wherein the methyl facet-chains are arranged alternately to left and suitable of the main chain) and atactic (wherein the methyl facet-chains are arranged randomly.) Syndiotactic polypropylene is the known stuff that washing-up bowls, buckets and bottle tops are created from. Atatctic polypropylene is one in all those sticky goo that would not have any makes use of that i understand of. i've got in no way particularly considered any of the isotactic polymer, so i don't understand what it seems or feels like.

Addition Polymerization if it is direct linking, and Condensation polymerization if water molecules are given out as bi-product.

Or, if you're in the US it is polymerization
