I'm writing my thesis and in order to explain the different polymers used, I would like to group them by "types" or "classes" (with similar chemical structure of the elemental unit and properties).
The polymers I'm talking about are:
Polysulfone (PSU), Polyphenylsulfone (PPSU), Polyethersulfone (PES) and Polyetehersulfone with Cardo group (PES-C). (See attached file)
Although I've found that Blanco et.al. and Yamagishi et.al. consider these polymers to belong to the same class, they differ in the name given to the "family".
So, I'm not really sure if:
(1) it is correct to group them
and, in case it is,
(2) which would be the correct name of the "family": poly(arylsulfones), polysulfones... ?
Polyarylsulfone is the most general family. All the cited polymers belong to this family
Poly(arylsulfone) is the correct terminology. Some people (including me at times) will call it "polysulfones" , but this creates confusion between the family and one of its members (the bis-A based polysulfone).
Same naming convention is used with the ketone group polymers (PEEK, PEK, PEKEK...) belonging to the poly(arylketone) family.
1. Yes.
2. Poly(arylsulfones) since all of these have aryl groups.
So, I think everyone has been in agreement with poly(arylsulfones).
Thank you very much for all of your answers, they've been really useful.
In my point of view, the PSU, PPSU PES PES-C are thermoplastics with some change in functional group and stereo-chemistry, rather they belong to same family, for more details I have pasted some links for further information, Please read them
