A polymer useful for preparing moldings and comprising essentially units of the formula I ##STR1## where R.sup.1 and R.sup.2 are each hydrogen or methyl, and

Poly(meth) acrylimides of improved color

At least 99% pure 2,2'[oxybis (methylene)]bis-2-propenoic acid

Preparation of oxadimethacrylic acid

A polymer useful for preparing shaped articles comprises essentially repeat units of the formula I ##STR1## where R.sup.1 and R.sup.2 are each hydrogen or methyl, and

N-aryl-substituted poly(meth)acrylimides

A process for isolating and purifying oxadimethacrylics of the general formula I

Isolation and purification of oxadimethacrylics

N-aryl-substituted poly (meth) acrylimides

A polymer comprising essentially units of formula I ##STR1## where R.sup.1 and R.sup.2 are each hydrogen or methyl, and

Poly(meth)acrylamides

Oxadimethacrylics useful for preparing pollers have the general formula I

Oxadimethacrylics and preparation thereof

Polymethacrylimides having a high heat resistance

A polymer comprising essentially at least two different repeat units of the formula I ##STR1## where R.sup.1 and R.sup.2 are each hydrogen or methyl,

Poly(meth)acrylimides with different n-substitutes

Copolymers are obtainable by (1) copolymerization of a monomer mixture of

Polymethacrylimides having high heat distortion resistance

Storage-stable solutions of film forming carboxyl-containing copolymers, from 5 to 80% of whose carboxyl groups have been reacted with glycidyl (meth)acrylate, in an inert organic solvent or solvent mixture additionally contain a phosphoric ester of a hydroxyalkyl (meth)acrylate and, if required, orthophosphoric acid, and photosensitive coatings which contain a photoinitiator, ethylenically unsaturated organic monomeric compounds which can be subjected to free radical polymerization and, if required, plasticizers, dyes, dye precursors and thermal polymerization inhibitors are produced in such storage-stable solutions. They are particularly suitable for the production of offset printing plates.

Storage-stable solution of a carboxyl-containing copolymer and

At least 95% tetrahydrofuran soluble polymers are obtainable by copolymerization of a monomer mixture of

Soluble polymers

Methacrylate (co)polymers containing carbazolyl side groups contain or are composed of repeating units of the general formula (I) ##STR1## where m is an integer of from 3 to 11. The novel methacrylate (co)polymers containing carbazolyl side groups can advantageously be used as photoconductors in photoconductive layers, in particular of electrophotographic recording elements.
