硬弹性材料是结晶或非结晶聚合物在特定的条件下加工而形成的，这类材料表现出高弹性、高模量和突出的低温弹性。
Hard elastic materials are a class of crystalline or non-crystalline polymers produced under special processing conditions, which show high modulus and high elasticity under very low temperature.
结晶质聚合物通常也比非结晶质聚合物更致密并且具有更好的机械性能。
Crystalline polymers also generally are denser and have better mechanical properties than amorphous polymers.
用于加强的微粒包含了陶瓷和玻璃之类的矿物微粒、铝之类的金属微粒以及包括聚合物和碳黑的非结晶质微粒。
Particles used for reinforcing include ceramics and glasses such as small mineral particles, metal particles such as aluminum, and amorphous materials, including polymers and carbon black.
流动场诱导聚合物结晶不仅是一个非平衡的热力学基础问题，对于指导聚合物加工过程和控制产品的最终性能有着同样重大的意义。
Flow-induced crystallization of polymers is not only a fundamental Nonequilibrium thermodynamic problem but also of importance for polymer processing and the final properties of polymer products.
根据各自的结构不同，聚合物可以是亲水的或憎水的（喜欢或讨厌水）、硬的或软的、晶体状的或非结晶质的、易起反应的或不易起反应的。
Depending on the structure the polymer may be hydrophilic or hydrophobic (likes or hates water), stiff or flexible, crystalline or amorphous, reactive or unreactive.
结晶度：聚合物可以是晶体状的或非结晶质的，但它们通常是晶体状和非结晶质结构的结合物(半晶体)。
Crystallinity. Polymers can be crystalline or amorphous, but they usually have a combination of crystalline and amorphous structures (semi-crystalline).
