Glass temperature of copolymers

Abstract According to a recent theory of the glassy state, chain stiffness is the main determinant of the glass transition. In this paper the theory is applied to the problem of...

Specific Heat of Atactic and Isotactic Polypropylene and the Entropy of the Glass

The specific heat of atactic and isotactic polypropylene has been measured from 80° to 490°K. The isotactic sample was 64.9% crystalline, as determined by specific volume, and t...

Effects of chronic hypertension and left ventricular hypertrophy on the incidence of sudden cardiac death after coronary artery occlusion in conscious dogs.

When acute myocardial infarction occurs in patients with hypertension and left ventricular hypertrophy (LVH), the incidence of sudden cardiac death increases markedly. Possible ...

The heat capacity of linear and branched polyethylene

The heat capacity of linear and branched polyethylene has been measured over the temperature range from 90°K. through the melting point. These and lower temperature data in the ...
