Thermosetting polymers - Classification of polymers
These are the polymers which go through permanent modification on heating. They get firm and infusible on heating. They are generally built from low molecular mass semifluid molecules. While heated they went highly cross linked to make hard infusible and insoluble components. The cross links take the atom in place that is why heating does not permit them to move liberally. Thus a thermosetting plastic is cross linked and is lastingly rigid.

i have a thermogram of magnesium oxalate and have to determine the mass lost in each step. And also calculate the number of water of hydration for each oxalate hydrate .
Step growth or condensation polymerisation In this form of polymerisation monomers usually consist of two functional sets, that is difunctional monomers. In that method no init
The maximum number of electrons accommodated in 5f orbitals are: (1) 5 (2) 10 (3) 14 (4) 18 Ans: 14
Which geometry does have Formaldehyde molecule The formaldehyde molecule has trigonal planar geometry. Therefore, both the H-C-H bond angle and the H-CAO bond angle are abou
The Ca 2+ and Mg 2+ ions in hard water form scum with soap. Therefore they don''t form lather and therefore don''t clean the dirt.
The reversible hydration of carbon dioxide The reversible hydration of carbon dioxide to carbonic acid is an acid-catalyzed addition of water that is mechanistically identical
