Abstract: A study of light scattering by surfaces of injection molded particle filled polymers is presented. In particular the effect that molding conditions have on surface roughness is studied by mechanical and optical profilometry as well as by light scattering. It is shown that Kirchhoff scalar theory with a Gaussian probability density of heights and a negative exponential correlation function between heights predicts reasonably well the surface scattering properties in an angular interval around the specular angle for all the molding conditions studied. This leads to a simple analytical model for gloss with only two parameters.
