Fluorocopolymers for oil repelling and waterproofing treatment of

The invention relates to fluoro copolymers containing hydroxyl groups and amino groups in salified or quaternized form. With such a copolymer and a polyisocyanate, an aqueous composition which is useful for the oleophobic and hydrophobic treatment of building materials may be prepared.

Cationic fluoro copolymers for the oleophobic and hydrophobic treatment

Fluorine-containing copolymers for use in coating substrates or for incorporation thereinto in order to impart water- and oil-repellent properties thereto are provided, starting from the following monomers:

Fluorine-containing copolymers and their use for coating and

The invention relates to fluorinated acrylic monomers of the formula: ##STR1## in which A and W denote divalent linkages, R is a hydrogen atom or a methyl radical, R.sub.F is a perfluoroalkyl radical and Q denotes an oxygen or sulphur atom or the group--NR'--, where R' denotes a hydrogen atom or an alkyl radical. Homo- or copolymers derived from these monomers are useful for the water or oil-repellent treatment of various substrates, particularly leather.

Fluorinated acrylic monomers as hydrophobic and oleophobic agents

The invention relates to fluorinated acrylic monomers of the formula: ##STR1## in which A and W denote divalent linkages, R is a hydrogen atom or a methyl radical, R.sub.F is a perfluoroalkyl radical and Q denotes an oxygen or sulphur atom or the group --NR'--, where R' denotes a hydrogen atom or an alkyl radical. Homo-or copolymers derived from these monomers are useful for the water or oil-repellent treatment of various substrates, particularly leather.

Fluorinated carbamate polymers as hydrophobic and oleophobic agents

The invention relates to fluoroacrylic monomers of formula: ##STR1## in which R.sub.f denotes a perfluoroalkyl radical, R is hydrogen or a methyl radical, R' denotes an alkyl or cycloalkyl radical, or --NR'-- denotes a 1, 4-piperazinylene radical, W and Z denote divalent connecting groups, Q is oxygen or sulphur or an --NR'-- group, R' denoting hydrogen an alkyl radical, and A is a C.sub.2 or C.sub.3 alkylene group. The polymers (homo- or copolymers) derived from these monomers may be used for the water-repellency and oil-repellency treatment of various substrates, particularly leather.

Fluoroacrylic monomers and polymers

The invention concerns the oilproofing and waterproofing treatment of construction materials by applying to them a composition which comprises by weight:

Compositions and process for the oilproofing and waterproofing treatment
