Abstract

The present invention relates to a thermally stable modified selectively hydrogenated high 1,2 content block copolymer wherein at least one acid compound is grafted to the block copolymer at a secondary or tertiary carbon position.

Independent Claims | See all claims (30)

  1. 1. A functionalized selectively hydrogenated block copolymer of the formula ABA to which has been grafted an acid compound or its derivative wherein,(1) each A is predominantly a polymerized monoalkenyl aromatic hydrocarbon block having an average molecular weight of about 2,000 to 115,000;(2) each B prior to hydrogenation is predominantly a polymerized conjugated diene hydrocarbon block having an average molecular weight of about 20,000 to 450,000;(3) the blocks A constituting 5-95 weight percent of the copolymer;(4) the unsaturation of the block B is less than 10% of the original unsaturation;(5) the unsaturation of the A blocks is above 50% of the original unsaturation;(6) and substantially all of the acid compounds or their derivatives are grafted to the block copolymer at secondary or tertiary carbon positions in the B blocks;(7) and wherein said acid compounds and their derivatives are not easily polymerizable.
  2. 2. A functionalized selectively hydrogenated block copolymer having at least 1 A mid block and at least two B end blocks to which has been grafted an acid compound or its derivative wherein,(1) each A is predominantly a polymerized monoalkenyl aromatic hydrocarbon block having an average molecular weight of about 2,000 to 115,000;(2) each B prior to hydrogenation is predominantly a polymerized conjugated diene hydrocarbon block having an average molecular weight of about 20,000 to 450,000;(3) the blocks A constituting 5-95 weight percent of the copolymer;(4) the unsaturation of the block B is less than 10% of the original unsaturation;(5) the unsaturation of the A blocks is above 50% of the original unsaturation;(6) and substantially all of the acid compounds or their derivatives are grafted to the block copolymer at secondary or tertiary carbon positions in the B blocks.
