cold,wet and damp conditions are needed because if they are in the sun for to long it wont work and it will explode....
from the science proffesors of oxford university hope we helped
(THIS IS A WARNING TO ALL STUDENTS ON HERE AND THAT HAVE USED THE internet FOR THERE EXAMS WE NO WHER YOU LIVE...)

How is polymerisation carried out?
There are 2 types:- Addition polymerisation is polymerisation in which monomers are joined across the double bond, for example polyethene. Condensation polymerisation is when water is lost from the two monomers for example the polymerisation of nylon, the two monomers are a diamine and dicarboxylic acid. From the amine an H goes and combines with and OH from the acid to form water. From this reaction, 2 moles of water are lostto form nylon -NH-[ ]-NH-C=O-[ ]-C=O-
What is polymerisation reaction?
Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
What is electropolymerization?
polymerisation in the presence of an electrical current
