The styrene monomer is a copolymer of ?-methylstyrene and another styrenic monomerer (e.g., styrene and vinyl toluene). Relative to the base butyl polymer, the cold flow properties of the butyl polymer composition are improved along with a number of other properties.Type: GrantFiled: July 24, 2001Date of Patent: March 29, 2005Assignees: Bayer Inc., Bayer AktiengesellschaftInventors: Richard Pazur, Anthony J. Sumner

Patent number: 6825278Abstract: A modified pressure sensitive adhesive (PSA) is produced by polymerizing at least one ethylenically unsaturated monomer to form a base polymer and reacting the base polymer with a modifying polymer comprising units derived from a n-vinyl lactam to thereby produce a modified polymer. The modified polymer can be used to form modified PSAs having improved adhesion properties over PSAs formed from the unmodified base polymer.Type: GrantFiled: January 16, 2003Date of Patent: November 30, 2004Assignee: Resolution Specialty Materials LLCInventors: Pavel Holub, Edita Moudra, Olga Bernatova, Jiri Horalek, Jiri Havranek
