    Abstract: THE RESISTANCE TO CREEP IS SUBSTANTIALLY IMPROVED IN BLOCK COPOLYMERS WHICH ARE SELECTIVELY HYDROGENATED AND HAVE WITHIN THE SAME BLOCK COPOLYMERIC MOLECULES NONELASTOMERIC BLOCKS A AND C AND ELASTOMERIC BLOCKS B WHEREIN, PRIOR TO HYDROGENATION, BLOCKS A ARE HOMOPOLYSTYRENE BLOCKS, BLOCKS B ARE CONJUGATED DIENE POLYMER BLOCKS AND BLOCKS C ARE HOMOPOLYMER BLOCKS OF ALPHA METHYL STYRENE; AND DUE TO HYDROGENATION, NO MORE THAN ABOUT 25% OF THE DOUBLE BONDS IN BLOCKS A AND C ARE REDUCED AND AT LEAST 90% OF THE ALIPHATIC DOUBLE BONDS OF BLOCKS B ARE REDUCED.

    Abstract: Very high-boiling hydrocarbon, such as petroleum residue, is converted to low-boiling liquid products by passing it through a continuous phase of a catalyst system selected from antimony trichloride, tribromide or triiodide; bismuth trichloride or tribromide; or arsenic triiodide; maintained at a temperature between 200* and 550* C. and under hydrogen partial pressure of at least 250 p.s.i. whereby the catalyst system performs the functions of acting as a hydrogenation catalyst, acting as a cracking catalyst, and providing a medium for maintaining the reactants in suitable relation to one another to promote reactions and obtain beneficial product distribution.
