cheap True Religion jeans polyamide atomicuch

Resin points of natural True Religion sale resins and synthetic resins. Natural resin obtained by the nature of animal and plant secretions.Amorphous organic matter, such as rosin, amber, shellac. Synthetic resin by imple organic compounds by chemical synthesis or?The resin product of some natural products by chemical reaction.Resin:A lot of resin classification, in addition to resin source can be divided into natural resins and synthetic resin, but also by Synthesis reaction and the main chains to be classified.

resin synthesis reaction classification.By this method can be resin into the addition polymer and condensation polymer. Addition polymer addition True Religion jeans polymerization reaction of polymerization?Material, the chemical formula of its chain structure and molecular formula of monomer, such as polyethylene, polystyrene, polytetrafluoroethylene.And so on.The condensation product obtained by the condensation polymerization reaction of the polymer, the chemical formula of its structural units and monomer formula.

Different, such as phenolic resins, polyester resins, polyamide resins, etc.2, according to the resin main chain composed of classification.By this method can be resin into the carbon-chain polymers, hybrid chain polymers and element-organic cheap True Religion jeans polymers.Carbon chain polymers of the polymer main chain, all the carbon atoms, such as polyethylene, polystyrene.Miscellaneous chain polymer is a polymer main chain is constituted by two or more carbon and oxygen, nitrogen, sulfur and other elements with atomicuch as POM, polyamide, polysulfone, polyether, etc..
