Polymers are provided, in which a pendant photoinitiator moiety is linked to the polymer structure via an amide or a succinimide.

In one aspect, a chelating phosphine-phosphonic diamide (PPDA) ligand is described herein for constructing transition metal complexes operable for catalysis of olefin polymerization, including copolymerization of ethylene with polar monomer.

A method of preparing PNVCL block polymers as the substrate for thermo-sensitive cultureware is provided. A hydrophobic polymer of poly n-butyl mathacrylate (PBMA) is obtained by atom transfer radical polymerization (ATRP) with typical haloalkane as an initiator. Further a thermo-sensitive block copolymer of poly n-vinyl caprolactam (PNVCL) is obtained by polymerization of N-vinyl caprolactam (NVCL) monomers using the hydrophobic PBMA polymer as a macroinitiator.

A number of variations may include a method including modifying fluorocopolymer polyols, diols, and related copolymers to make polymerizable materials through polymerizable unsaturation. A number of variations may include products, for example but not limited to coatings, films or painting including modifying fluorocopolymer polyols, diols, and related copolymers.

Disclosed is a hydrophilic copolymer including more than 50% by mol of a structural unit derived from a polymerizable monomer (A) from which a homopolymer having a lower critical solution temperature (LCST) is formed, a structural unit derived from a polymerizable monomer (B) having at least one group selected from the group consisting of a sulfonic acid group (−SO.sub.3H), a sulfate group (−OSO.sub.3H), a sulfurous acid group (−OSO.sub.2H), and a group of salts thereof, and a structural unit derived from a polymerizable monomer (C) having a photoreactive group. Also disclosed is a medical device including the hydrophilic copolymer. The medical device exhibits high sliding property until it reaches a target lesion, and low sliding property after reaching the target lesion. Methods of making and using the hydrophilic copolymer and medical device are also described.
