A process for synthesizing a polymer bearing at least one phosphonate group in the polymer chain is provided. The process comprises at least the reaction of a starting polymer bearing at least one nucleophilic function in the polymer chain with at least one electrophilic compound bearing both a phosphonate group and an electrophilic function. The electrophilic function is selected from the halide function, the acyl halide function, the ester function, the carboxylic acid function and the isocyanate function.

A display unit that includes an image display part and a light-transmitting protective part arranged on the image display part. A cured resin layer is arranged between the display part and the protective part. The cured resin layer has a transmittance of 90% or higher in the visible range and a storage modulus at 25 C. of 110.sup.7 Pa or less. The cured resin layer is formed from a resin composition that has a cure shrinkage of 5% or less.

An organic silicon compound-modified copolymer having structural units represented by formula (1) and formula (2) and having a hydroxyl group at at least one end has excellent compatibility with alcohol compounds and isocyanate compounds and also gives a cured product having excellent water repellency and moisture resistance.

The present disclosure provides a multi-base material adaptivity pulling removal type binder product, a binder composition and an assembly. The binder product contains an acrylic acid copolymer, a flexibilizer, tackifying resin and an isocyanate curing agent. The binder product comprises a binder layer formed by curing at least a part of the binder composition. The assembly is formed by bonding the binder layer. The binder can be used for firmly bonding various base materials, comprising both high surface energy base materials and low surface energy base materials; meanwhile, the binder can be pulled and removed from the base materials at a large angle. The binder is particularly suitable for the fields of smartphones, tablet computers and a newly developing electronic market.
