✦ Synopsis

Akstraet--Polymerization of tetrafluoroethylene (TFE) in an aqueous medium using a redox system in the presence of a hard disperse filler leads to polymerization-filled polytetrafluoroethylene (PTFE). The influences of various factors on the polymer yield, the conversion of TFE and the degree of filling were studied. The kinetic dependencies concerning the polymerization-filling of PTFE with CaCO 3 were studied. The reaction order, activation energy and the ratio of rate constants for chain propagation and termination were determined.

The paper considers the possibility of synthesizing polycaprolactam on the basis of acid-base interaction of the caprolactam with a filler surface (calcium phosphate), without using initiating systems. The surface acidic properties of the filler are estimated by using the method of butylamine titrat

Most laboratory investigations on the tribological behaviours of polymers are done on the rigs which are in line with pin-on disc or pin-on ring models. But bearings have special geometrical and kinematical characteristics. That is why obtained results can only give a rough idea. In this study, the

Using a plasma-induced graft polymerization technique, which is well known as a surface modification method, the grafted polymer was formed in pores of the porous material. This study examined the filling mechanism. Five thin porous films were sandwiched together, and employed as the substrate. The
