The invention is directed towards a composite membrane comprising an ionic branch polymer and at least one other polymer, to form a polymer blend.

But, unlike cellulose, starch is a branched polymer.

The randomly branched polymer can have high molecular weight and broad molecular weight distribution.

The polymeric material contains a metallocene catalyzed branch copolymer which has rubber-like properties.

The catalyst is prepared by an extrusion method using a comb-branched polymer as an extrusion aid.

These compositions comprise a branched polymer product containing hydrophilic groups, i.e., comb polymer, comprising one or more branch polymer segment(s) chemically linked along a linear polymer backbone segment.

The metal fine particle-dispersing agent may be composed of a branched or linear polymer represented by the following formula (1) or formula (4).

Disclosed is a metal microparticle-dispersing agent comprising a branched polymeric compound having an ammonium group.

The photoresists comprise (a) a branched polymer containing protected acid groups and (b) at least one photoacid generator.

A continuous process for making a comb-branched copolymer of an acrylic monomer and a polyether macromonomer is disclosed.

The present invention also provides a method for producing a phase separated, branched, copolymer hydrogel comprising a mixture of a hydrophilic polymer and a polymer chain modifying agent.

The branch polymer is an ionic polymer and typically is selected from dendrimers, arborols, polycations, polyanions and polyamphiphiles, including in certain instances polethylenimine (PEI) or dextransulfate.

This kind of branched type siloxane polymer is stably anchored in the network structure and provides continuous conducting paths in all directions throughout the IPN solid polymer electrolyte.

Disclosed is a process for preparing a branched polymer, belonging to the fields of polymer synthesis and preparation of functional polymers.

Provided is a dendrimer particle having a unit that contains a fluorine atom at a plurality of branch ends of an aliphatic branched polymer (dendrimer).
