Embodiments for a crosslinked alkoxysilyl polynorbornene homopolymer and methods of making crosslinked alkoxysilyl polynorbornene homopolymer are provided, where the method comprises polymerizing through addition polymerization or ring opening metathesis polymerization a norbornene monomer comprising an alkoxysilyl moiety in the presence of a catalyst to produce an alkoxysilyl modified polynorbornene homopolymer, and producing a crosslinked alkoxysilyl polynorbornene homopolymer through sol-gel initiated crosslinking of the alkoxysilyl modified polynorbornene homopolymer at ambient conditions, or acid-catalyzed conditions.

The invention generally relates to synthetic mimics of cell penetrating peptides. More particularly, the invention relates to certain novel monomers, oligomers and polymers (e.g., co-polymers) that are useful for the preparation of synthetic mimics of cell penetrating peptides, their compositions, preparations and use.

Described herein, inter alia, are compositions of cell penetrating high density brush peptide polymer, drug delivery vehicles for delivering cell penetrating peptides and drugs. Also provided is a methodology for protecting active peptides from proteolysis by packaging them into high-density brush polymers via ring opening metathesis polymerization (ROMP), using an easily-prepared catalyst initiator. The graft-through polymerization of norbomyl-peptide monomers via ROMP can result in structures that resist proteolysis relative to their monomeric analogues in a manner dependent on their degree of polymerization (REFS). Polymerized peptides, while protected from proteolysis, maintain their intended biological function and are capable of any of the functions inherent to the peptide, such as binding a receptor or ligand, initiating a signaling pathway, penetrating a cell, or inducing a therapeutic effect.

The present invention provides a hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer having a melting point of lower than 280 C., an initial melting temperature of 260 C. or higher and a syndiotacticity of higher than 90%, and a syndiotactic dicyclopentadiene ring-opening polymer, and a method for producing the syndiotactic dicyclopentadiene ring-opening polyme, and a method for producing the hydrogenated syndiotactic crystalline dicyclopentadiene ring-opening polymer.
