  2. 4. is an agent with the capacity to cause cancer in humans.
  3. 6. is a chain of chemically linked one type of small molecules (or monomers),
  4. 7. is a process of reacting monomer molecules together in a chemical reaction to form polymer chains.
  5. 11. is a polymer derived from more than one species of monomer.
  6. 15. a chemical that will cause an allergic reaction in a substantial number of exposed people.
  7. 16. are derived from petroleum oil, and made by scientists and engineers.
  8. 17. the crystal is described by vectors of unequal length.
  9. 18. are typically viscous substances that convert into rigid polymers through a curing process.
  10. 19. the ability of the plastic to resist abrasion and wear.
  11. 20. has three axes that all meet at 90 degrees.
  12. 21. a substance added to a product (as to increase bulk, weight, viscosity, opacity, or strength)
  13. 24. is used to coat a variety of products because it's waterproof, cuts down on friction, and creates a nonstick surface.
  14. 28. one of the structural categories systems to which crystalline solids can be assigned.
  15. 31. is a thermoplastic “addition polymer” made from the combination of propylene monomers.
  16. 34. is a category of polymers that contain the ester functional group in every repeat unit of their main chain.
  17. 35. are polymers in which a crosslinking reaction occurs promoting chemical bonding between macro molecular chains.
  18. 36. is a substance that is added to a material to make it softer and more flexible.
  19. 37. is the simplest repeating unit in a simple cubic structure​.
  20. 38. is a field of research and innovation concerned with building 'things'.
Down
  1. 1. is any artificial elastomer, synthesized from petroleum byproducts.
  2. 3. are defined as polymers that can be melted and recast almost indefinitely. They are molten when heated and harden upon cooling.
  3. 5. are nanomaterials that nanosized polymers built from branched units.
  4. 8. a chemical that causes birth defects.
  5. 9. an infinite periodic array of points in a space.
  6. 10. a chemical that damages chromosomes.
  7. 12. is produced from plants and is classified as a polymer.
  8. 13. is a solid material whose constituents are arranged in a highly ordered microscopic structure.
  9. 14. substance is one that will damage or destroy other substances with which it comes into contact by means of a chemical reaction.
  10. 15. is a polymer made up of siloxane.
  11. 22. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units, each a relatively light and simple molecule.
  12. 23. are simply a combination of two or more constituent materials with different physical or chemical properties.
  13. 25. a tough elastic polymeric substance made from the latex of a tropical plant or synthetically.
  14. 26. are referred to three axes of unequal lengths.
  15. 27. a substance that causes slight inflammation or other discomfort to the body.
  16. 29. is a process of heating a thermoplastic sheet to its softening point.
  17. 30. is a thermoplastic silky material, generally made from petroleum, that can be melt-processed into fibers, films, or shapes.
  18. 31. is a wide range of synthetic or semi-synthetic materials that are used in a huge and growing range of applications.
  19. 32. is a lightweight, durable thermoplastic with variable crystalline structure.
  20. 33. refers to the degree of structural order of a solid.
