(co)polymers by photopolymerization |
| abstract |
A process for the selective preparation acrylate- or methacrylate-homo- or acrylate- or methacrylate-co-oligomers with a weight average molecular weight (Mw) from 1000 to 20000, a polydispersity « 3 and a conversion of the monomers to polymers greater than or equal to 70 %, or for the selective preparation of polyvinylacetate and its hydrolysis product polyvinylalcohol with a weight average molecular weight (Mw) from 1000 to 25000, a polydispersity « 3 and a conversion of the monomers to polymers greater than or equal to 70 %, is characterized in that a mixture of the corresponding monomers is irradiated in the presence of a specific photoinitiator or photoinitiator mixture at a temperature from -20 to 70 °C in an inert solvent or inert solvent mixture, with light of a wavelength from 305 to 450 nm, wherein the contents of monomers in the reaction mixture is up to 70 %. |
