Functionalized copolymers of isoolefins and conjugated diolefins, methods of preparing the copolymers, and their use as compatibilizers are disclosed. The diolefin monomer units of the co-polymer are modified at the C&#x2014;C double bond along the backbone of the copolymer to include an oxygen containing functional group such as epoxide, ester or alcohol. The functionalized copolymers improve the wettability of a non-hydrophilic surface towards hydrophilic polymer and allows for the formation of homogenous layers of the hydrophilic polymers. In particular, the spreading of a hydrophilic polymer on a non-hydrophilic substrate is facilitated by applying the co-polymers as an interfacial layer between the two incompatible materials. The resulting coated substrates exhibit resistance to protein adsorption and cell growth after grafting. The co-polymers are especially suited in the coating of biomedical devices where a high degree of uniformity of the coated surface is required.

Functionalized copolymers of isoolefins and diolefins and their use as compatibilizers

Self-immolative polymers degrade by an end-to-end depolymerization mechanism in response to the cleavage of a stabilizing end-cap from the polymer terminus. Examples include homopolymers, mixed polymers including block copolymers, suitable for a variety of applications. A polyglyoxylate can be end-capped or capped with a linker as in a block copolymer.

Polyglyoxylates, manufacture and use thereof

The present invention relates to novel graft copolymers of functionalized poly(isoolefin-co-conjugated diolefin, and a process of preparing such graft copolymers. The present invention also relates to a method of preparing functionalized copolymers of isoolefins and conjugated diolefins.

Methods for preparation of novel graft copolymers

A method of forming a polyelectrolyte polymer by photopolymerizing a monomer having an ionic group covalently linked to a photocurable group. The ionic group can be borate and/or phosphonium ion. The polymer can be cross-linked as by diacrylate.
