The effect of temperature on the strength of linear thermoplastics is that: |
| A. | as the temperature of thermoplastics increases, they cure by cross-linking and forming a three-dimensional network of covalent bonds, increasing the strength of the thermoplastic |
| B. | same effect as (a), except that as the temperature gets sufficiently high, the covalently, bonded network weakens and eventually burns |
| C. | nothing happens. Temperature doesn t affect thermoplastics |
| D. | as the temperature of thermoplastics is increased, the secondary atomic bonds weaken and the material softens |
