| titleOfInvention | Process for preparing vinyl phenol polymers and stabilized compositions of vinyl phenol-containing polymerization raw material |
| abstract | Vinyl phenol polymers are useful materials having manynapplications. Vinyl phenol polymers possessing an appropriatenmolecular weight corresponding to each of the applications arendesired. However, it is very difficult to control thenmolecular weight of vinyl phenol polymers, because vinylnphenol monomer exhibits a very high reaction rate in thenpresence of a radical initiator, and it is very difficult tonobtain vinyl phenol polymers having molecular weight of fromnseveral thousands to one hundred and several tens ofnthousands. Further, vinyl phenol monomer is very difficult tonstore, because it is rapidly polymerize even at roomntemperature. A simple process for preparing vinyl phenolnpolymers having the molecular weight range mentioned above bynsimply adding methanol to the polymerization system isndisclosed. A stabilized composition of vinyl phenol suitablenfor use to prepare vinyl phenol polymers, comprising vinylnphenol-containing polymerization raw material and methanol asnthe indispensable constituents is also disclosed. |
