Abstract
A Pickup tackmeter was partially modified to prolong the autohesion measurements on raw rubber samples up to the order of 103min. The dependence of the maximum tack strength, F, on the time of contact, tp, in the longer time region could always be approximated by the following empirical equation, <br>F=F0+(F∞-F0)(1-e-tp/τp).<br>Here F0 and F∞ are the numerical parameters independent of tp. The constant, τp, which is a measure of the rate process of the autohesion, was found to be roughly proportional to the 3.4th power of the average molecular weight of the sample for SBR. This finding on τp would suggest that the mobility of rubber molecules is an important factor to the autohesion process.
