A film formed from a solvent solution contains the polymer of .5. A device made from a film contains the polymer of . This invention relates to the field of asymmetric regio-regular conjugated polymers and their use in electronic-optical and electronic devices. More particularly, this invention relates to regio-regular conjugated semiconducting polymers containing asymmetric fluorine substituted (2,1,3)-benzothiadiazole in backbone. The invented asymmetric regio-regular conjugated polymers are soluble in common organic solvents for printing thin film devices such as organic photovoltaic devices (OPV), organic photo detectors, organic thin film transistors (OTFT) and organic sensors.Conjugated polymers consist at least of one backbone chain of alternating double and single bonds. The π-electrons in conjugated polymers are delocalized and can be easier moved from one bond to the other, what makes such conjugated polymers to be a kind of organic semiconductors, thus referred as semiconducting polymers as well.Generally, semiconducting polymers are created via cross-coupling condensation reactions with symmetrical monomer units that produce linear polymer backbone configurations. When symmetric monomer units are involved, various regiochemistries between adjacent structural units along the backbone vector can be created. As an example. Scheme-1 demonstrates the possible polymer chain configurations can be generated from monomer 3-hexylthiophene. The electronic properties such as charge mobility in organic thin film transistor (OTFT) and power conversion efficiency (PCE) in organic photovolatic (OPV) devices have been shown to be strongly dependent on the configuration of polymer backbone. Higher performance has been generally observed for these polymers with higher regioregularity. A high regioregularity means a ...

The SMSHP has thermally reversible repeating units where a thermally reversible adduct is situated between two common linking units formed during a polymerization process between thermally reversible monomers and cross-linking monomers. Optionally, other repeating units can be present from other monomers. Shape-memory results when the SMSHP is warmed to a temperature in excess of its glass transition temperature and self-healing then proceeds when a higher temperature is achieved where thermally reversible adducts dissociates to complementary groups that subsequently reform the adduct without distortion of the memorized shape. The thermally reversible adducts can be Diels-Alder (DA) adducts in a polyurethane, poly urea, or amine epoxy SMSHP network. 1.

The resin layer contains a resin composition and a solvent and the solvent is present in a total amount of at least 5 wt % based on the total weight of the resin layer. The dry film of the present invention can be applied onto a substrate without the use of a prior art vacuum lamination apparatus. The application process is simple and is more cost-efficient than the prior art techniques.

The present invention provides: an assembly obtained by bonding a sheet made of a modified hydrogenated block copolymer having an alkoxysilyl group introduced therein with a thermoplastic resin sheet, wherein a peel strength of the adherend surface is 4 N/cm or higher; a method for producing an assembly by bonding a sheet made of a modified hydrogenated block copolymer having an alkoxysilyl group introduced therein with a thermoplastic resin sheet, the method comprising steps of: (1) activating an adherend surface of the thermoplastic resin sheet with at least one selected from plasma exposure, excimer UV exposure and corona discharge; and (2) superposing the sheet made of the modified hydrogenated block copolymer having the alkoxysilyl group introduced therein with the adherend surface of the thermoplastic resin sheet to be subjected to thermally press-bonding; and a sheet made of a modified hydrogenated block copolymer, comprising at least one surface activated. 1. An assembly obtained by bonding a sheet made of a modified hydrogenated block copolymer having an alkoxysilyl group introduced therein with a thermoplastic resin sheet , whereina peel strength of the adherend surface is 4 N/cm or higher.2. A method for producing an assembly by bonding a sheet made of a modified hydrogenated block copolymer having an alkoxysilyl group introduced therein with a thermoplastic resin sheet , the method comprising steps of:(1) activating an adherend surface of the thermoplastic resin sheet with at least one selected from plasma exposure, excimer UV exposure and corona discharge; and(2) superposing the sheet made of the modified hydrogenated block copolymer having the alkoxysilyl group introduced therein with the adherend surface of the thermoplastic resin sheet to be subjected to thermally press-bonding.3. The method for producing the assembly according to claim 2 , whereinthe step (1) is a step of activating both surfaces of the adherend surface of the sheet made of the ...
