The elasto‐viscous and stress‐optical properties of commercial methyl methacrylate polymer have been measured. Between 66°C and 107°C Young's modulus drops from approximately 400,000 pounds per square inch to roughly 200 pounds per square inch and the material behaves like rubber. At 93°C...
Experimental values of second‐order transition temperatures T m and of cubical expansion coefficients below and above this temperature are presented for several new materials, notably saran. The thermal expansion behavior of two‐component systems of incompatible materials (polystyrene plus...
Vulcanized rubber is composed of a cross‐linked network of chain molecules, segments of which are sufficiently free and mobile in localized regions to form a crystal lattice upon stretching. The crystallites thus formed represent an automatic molecular mechanism for re‐enforcement and are...
An extrusion plastometer for rubberlike materials which measures the shearing stress at a predetermined constant average rate of shear and a given temperature is described. In one filling of the extrusion chamber, requiring about 10 cm 3 of sample, the average rate of shear is set at 3 or 4...
Natural rubber is the prototype of an important class of materials consisting of long flexible molecules which interact with each other in a particular way. Some of the properties of bulk rubber are strikingly similar to, and may be understood by a consideration of, those of single flexible...
Drift tests lasting 8 years have been carried out on rubber blocks in compression at 35°C. Rate of drift, initially high, attains a low constant value in 200 days or less. The initial, rapid drift is termed transient drift; and the slower, constant drift is termed steady drift. Drift varies...
