摘要:
A method for formation of a polymer film in-situ according to the invention comprises steps of: providing a polymerizable composition in one or multiple parts; initiating polymerization of the polymerizable composition to form a polymerizing composition; prior to completion of polymerization of the polymerizable composition, forming a film therefrom; and fully polymerizing the polymerizing composition to form the polymer film.

Cover seals for sealing of a re-workable hard disk drive comprise: a metallic substrate; an outwardly exposed adhesive layer on at least a portion of a major surface of the metallic substrate; and an adhesive-free border comprising a fusible metal alloy layer surrounding the adhesive layer. The cover seals can be used to form sealed hard disk drives, wherein a cover seal is attached to an exterior surface of the cover of an enclosed hard disk drive housing so that an adhesive layer of the cover seal covers the entire junction where the base and cover components of the enclosed housing meet and a metallic joint adheres a perimeter of the cover seal to the base of the enclosed housing.

In one embodiment, an apparatus for continuous production of a partially polymerized composition comprises: a reactor for formation of monomer to be partially polymerized; and a polymerization reactor for continuously receiving the monomer to be partially polymerized from the reactor in which it is formed and partially polymerizing the monomer. In another embodiment, an apparatus for continuous production of a partially polymerized composition comprises: a polymerization reactor for continuously receiving monomer to be partially polymerized and for partially polymerizing the monomer therein, wherein the polymerization reactor comprises an essentially straight tube for a heating portion and wherein the heating portion is essentially free of internal mixing apparatus.
