Formulation and evaluation of a hydrophobic composite plastic

A hydrophobic co-polymer, helptafluorobutylmethacrylate co-para vinyl phenol, was compounded with ethylene glycol dimethacrylate and silanated quartz to produce a hydrophobic composite. The experimental composite had satisfactory working properties and had mechanical properties comparable to commercial composite but a higher modulus of resilience. The wear resistance was equal to or greater than the commercial composite depending on whether a two-body abrasion test or a track width versus normal load test was used for the evaluation. The thermal coefficient of expansion and water sorption values were somewhat higher than those of commercial composites.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74217/1/j.1365-2842.1980.tb00454.x.pd
