Yes，Plastics can be classified by chemical structure, namely the molecular units that make up the polymer's backbone and side chains. Some important groups in these classifications are the acrylics, polyesters, silicones, polyurethanes, and halogenated plastics. Plastics can also be classified by the chemical process used in their synthesis, such as condensation, polyaddition, and cross-linking.
What else can I help you with?
What charge develops on rubbing plastic straw with polythene?
When you rub a plastic straw with polythene, the plastic straw becomes negatively charged due to the transfer of electrons between the materials. Electrons are transferred from the polythene to the plastic straw, leaving the straw with a negative charge.

Why is polythene called thermoplastic?
Polythene is also known as polyethylene. Polythene is a type of plastic that is widely used in packaging and many of the plastic products we use today. You see polythene in all shapes and sizes. Polythene is such a widely used product because it is easy to bend it and mold it into the shape that you want. This action of molding the plastic is called thermosetting. Polythene is heated to high temperatures and molded into the shape that is desired. Then the object is set aside and cooled. Once the object is at room temperature (or close to it) the object will not break or bend so readily. Now, if you take the prefix of thermosetting you just have "thermo." Thermo is typically used with words meaning temperature or heat. Because polythene is a plastic and it can be set in its shape by heat, it is called thermoplastic.
