Alpha methyl styrene and vinyl toluene and processes of preparation |
| abstract |
The specification discloses resinous compositions comprising copolymers of alpha methyl styrene and vinyl toluene, 95 percent by weight of said copolymers having molecular chain lengths less than 100 Angstroms. The compositions are characterized by softening points in the range of about 10 to 98 DEG C and good solubility in paraffin wax. Processes are disclosed for preparing said compositions by copolymerizing mixtures of monomers of vinyl toluene and alpha methyl styrene in a weight ratio in the range of 2.5:1 to 4.5:1 in the presence of an acid clay catalyst. |
