A study has been made of the effect of increased time of mixing carbon black in rubber on the dynamic properties of the carbon black-rubber vulcanisates. Increased time of mixing reduces the dynamic modulus and dynamic viscosity as well as the phase angle at moderate amplitudes of oscillation. The c

## Abstract The heats of polymerization for two unsaturated polyester resins are presented using two free radical initiator systems. The first was 1% methyl ethyl ketone peroxide/0.2% cobalt octoate (12%) and the second was 2% benzoyl peroxide/0.2% dimethylanyline. The heats of reaction were measur
