Influence of structure of polyethylene oxide films on their failure in cyclic bending
Conclusions In PEO films produced from Soviet raw material, when tested in cyclic bending, even in the first few load cycles, “silver cracks” (crazes) begin to appear, whereas in the non-Soviet analogs, there are hardly any such cracks in the first 200 cycles. With further loading, the number of SCs...

Influence of structure of polyethylene oxide films on their failure in cyclic bending |
| abstract |
Conclusions In PEO films produced from Soviet raw material, when tested in cyclic bending, even in the first few load cycles, “silver cracks” (crazes) begin to appear, whereas in the non-Soviet analogs, there are hardly any such cracks in the first 200 cycles. With further loading, the number of SCs in both batches increases, but in the Soviet specimens the numbers are considerably greater.The degree of crystallinity of films based on the Soviet raw material is lower than in films produced from the non-Soviet material. In synthesis of a polymer film, the symmetry of joining the monomer units breaks down, and this leads to the formation of weak bonds in the molecular chain and the appearance of possible stress concentrators. © Plenum Publishing Corporation 1992 |

Conclusions In PEO films produced from Soviet raw material, when tested in cyclic bending, even in the first few load cycles, “silver cracks” (crazes) begin to appear, whereas in the non-Soviet analogs, there are hardly any such cracks in the first 200 cycles. With further loading, the number of SCs in both batches increases, but in the Soviet specimens the numbers are considerably greater.The degree of crystallinity of films based on the Soviet raw material is lower than in films produced from the non-Soviet material.
