Notizen: Certain physical and chemical properties of samples of polyacetaldehyde prepared by M. Letort have been examined. Study of the rheological behavior of high molecular weight specimens of this polymer indicates that its internal strength is high, and that it shows typical rubbery elasticity. Under rapidly applied stresses, it shows a high modulus, indicating a high degree of internal friction. Correlated with this is a relatively high brittle point. Upon pyrolysis the polymer depolymerizes to yield the monomer, and likewise undergoes chain cleavage. About 200-400 monomer units are lost for each cleavage of the chain.
