Patent number: 5512642Abstract: An improved process for making vinyl aromatic/allylic alcohol copolymers is disclosed. Gradual addition of a free-radical initiator during the course of the polymerization results in a substantial increase in the polymer yield obtained compared with the yield from conventional processes in which all of the free-radical initiator is charged initially. The process is particularly useful for making commercially important varieties of styrene-allyl alcohol copolymers.Type: GrantFiled: April 7, 1995Date of Patent: April 30, 1996Assignee: Arco Chemical TechnologyInventor: Shao-Hua Guo
