Provided is a transparent member having formed thereon a film having high reliability, the film being capable of suppressing an increase in its haze and maintaining its hydrophilicity for a long time period even when exposed to an outdoor environment. The transparent member is a transparent member including a resin base material and a porous layer arranged thereon, wherein the porous layer has a network structure in which silica particles are joined to each other with a binder, wherein the resin base material has a mixed layer that the network structure has entered, wherein the mixed layer has a thickness of 20 nm or more and 160 nm or less, and wherein a thickness variation in a range having a length of 1 m of a section of the mixed layer in its thickness direction along the surface of the resin base material is 15% or less.

The present invention generally relates to a method of reducing contamination from plastics. The resulting purer plastic can be used in demanding applications.

A process for continuous production of partly crystalline polycondensate pellet material which comprises the step of crystallizing the pellet material in a second treatment space (6a) under fixed bed conditions by supply of energy from the exterior by means of a process gas, wherein the process gas has a temperature (T.sub.Gas), which is higher than the sum of the pellet temperature (T.sub.GR) and the temperature increase (T.sub.KR) which occurs due to heat of crystallization released hi the second treatment space (6a), i.e., (T.sub.Gas>(T.sub.GR+T.sub.KR)). The pellets at the exit from the second treatment space (6a) have an average temperature (T.sub.PH), which is 10 to 90 C. higher than the sum of the temperature of the pellets (T.sub.GR) and the temperature increase (T.sub.KR) which occurs due to heat of crystallization released in the second treatment space (6a), i.e., (T.sub.GR+T.sub.KR+90 C.)T.sub.PH(T.sub.GR+T.sub.KR+10).
