1.Additives are external substances purposely added to change properties of polymers or resins.
2.Most polymers are flammable in their pure form, except（）.
3.Fillers are most often added to improve tensile strength, and（）.
4.Thermosetting polymers have the distinct advantage of being chemically and thermally resistant materials used in many high-performance applications.
5.Thermoset polymers are generally harder and stronger than thermoplastics and have better dimensional stability.
6.Thermoplastics are mainly prepared by addition polymerization.
7.Examples of common thermoplastic polymers include（）.
8.Poly(1,4-cis-butadiene) has a higher Tg than Poly(1,4-trans-butadiene) because the cis -form reduces the energy barrier for rotation of adjacent bonds.
9.PVC and PAN have a lower Tg than amorphous polypropylene.
