| titleOfInvention | METHOD FOR PRODUCING ALPHA METHYL STYRENE-STYRENE DIISOBUTENIC HYDROCARBON RESINS |
| abstract | The invention relates to a process for the preparation of * methylstyrene-styrene-diisobutene hydrocarbon resins, wherein it has been found that both diisobutene, Di &sub2;, diisobutene mixtures and isobutene oligomers with C & ind8 !, C & ind12! And C & ind16! Isoolefins are used as diisobutene source , dried or undried, and that both purified and dried and commercial solvents without pretreatment can be used as solvents. Suitable coinitiators for the polymerization are alkylaluminum chlorides, while water or alkyl halides, preferably t-butyl chloride, are used as initiators. With the use of aluminum organyls as coinitiators, it has been found possible to obtain in very high yields hydrocarbon resins which have almost the same composition as the comonomer concentration ratio used. Furthermore, it has been found that * methylstyrene is substitutable by styrene in all ratios. Due to the properties of the monomers, products are obtained which have a molecular weight of 350-2500 g / mol. Thus, a possibility has been found which makes it possible to produce water-clear hydrocarbon resins for a variety of applications using the much less hazardous and hence easier to handle diisobutene instead of isobutene and * methyl styrene and optionally in high yields, whereby disadvantages of known processes can be excluded , |
