To provide a method for producing a fluorinated polymer which does not require an emulsifier as an essential component while an aqueous medium with little environmental burden is used.

A method for producing a fluorinated polymer, which comprises polymerizing at least one fluorinated monomer selected from tetrafluoroethylene, chlorotrifluoroethylene and vinylidene fluoride, in an aqueous medium in the presence of a first polymer having units based on a compound represented by the following formula (1):

CXY═CR.sup.1-L-R.sup.2  (1)

wherein X and Y are each independently a hydrogen atom, a halogen atom or a methyl group, R.sup.1 is a hydrogen atom, a halogen atom or a C.sub.1-3 alkyl group, L is —CO—O—*, —O—CO—* or —O—, provided that * represents the binding position to R.sup.2, and R.sup.2 is a cyclic alkyl group, a monovalent aromatic hydrocarbon group or a C.sub.1-6 linear alkyl group, provided that the C.sub.1-6 linear alkyl group as R.sup.2 may have an etheric oxygen atom in a carbon-carbon bond, and the hydrogen atom in the cyclic alkyl group, the monovalent aromatic hydrocarbon group or the C.sub.1-6 linear alkyl group as R.sup.2 may be replaced with a halogen atom.

This invention relates to a carbamate functional thermosetting coating with a composition comprised of a carba-mate-functional acrylic and/or polyester polyol and an alkylated melamine-formaldehyde cross linker modified by an aliphatic polyester and an alkylated melamine. The polyester polyol is made of monomers including a 2,4,4-tetraalkylcyclobutane-1,3-diol and an aliphatic diacid. These polyester polyols can be used in blends with hydroxyl-functional or carbamate-functional acrylic resins or serve as the primary film former in a coating formulation.
