Abstract: A polymer is prepared from monomers containing at least one carbon to carbon double bond and at least one siloxane moiety and from monomers containing at least one carbon to carbon double bond and at least one moiety that imparts reactivity to the resulting polymer. Siloxane moieties impart permeability; reactivity is obtained from monomers containing epoxy, oxetane, oxazoline, benzoxazine, or episulfide functionality. Additional properties can be added to the polymer by the inclusion in the initial polymerization mix of monomers that impart low glass transition temperature, high glass transition temperature, and adhesion. The level of each functionality can be controlled by the practitioner by varying the amount of monomer containing that functionality added to the initial polymerization. These materials can be B-staged.

Abstract: The present invention provides a compound that is a terpolymer of: (a) at least one ethylenically unsaturated linear or branched compound that has at least one fluorine atom covalently coupled thereto; (b) at least one ethylenically unsaturated precursor of a cyclic or polycyclic compound that has at least one fluorine atom covalently coupled thereto forming a cyclic or polycyclic decrystallizing monomer in said terpolymer; and (c) at least one ethylenically unsaturated functional compound which as a monomer in said terpolymer changes solubility upon exposure to an acid or base.
