Provided herein is a hot melt pressure sensitive adhesive comprising one or more styrene block copolymers, a tackifier, and polyisobutylene plasticizer, wherein the adhesive contains less than 1 wt % of a plasticizer oil. The adhesive can be used in a label construction along with a facestock such as a polyethylene facestock, wherein the swelling factor of the facestock is reduced as compared to the swelling factor of the facestock in labels that include a plasticizer oil. Also provided are methods for producing and using the hot melt adhesive, and articles labeled with the hot melt adhesive.

Low molecular weight, high Tg resins, with applications including tire additives and adhesives. An oligomer is obtained by ring opening metathesis polymerization (ROMP) of a sterically encumbered cyclic monomer with an olefinic chain transfer agent. The sterically encumbered cyclic monomer and the olefinic chain transfer agent are present in the polymerization at a molar ratio of from 2:1 to about 40:1. Also, methods for making the oligomer by ROMP.

Articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a multilayered modification (coating) layer, for example an alternating cationic/anionic polymer coating layer, and associated deposition methods, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature (≤400° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.

The present invention relates to photosensitive compositions containing polynorbornene (PNB) polymers and certain additives that are useful for forming microelectronic and/or optoelectronic devices and assemblies thereof, and more specifically to compositions encompassing PNBs and certain multifunctional crosslinking agents, and two or more phenolic compounds which are resistant to thermo-oxidative chain degradation and exhibit improved mechanical properties.

The polymerization of cycloalkenamer is stopped by adding an alkyl vinyl derivative. Subsequently compound A is added, wherein compound A has at least one of the features i) or ii): i) at least one functional group or ii) at least one saturated or unsaturated aliphatic or aromatic heterocyclic ring having 3 to 14 ring atoms, wherein the ring atoms contain at least one carbon atom and at least one atom selected from oxygen, nitrogen and sulfur. A membrane filtration is subsequently carried out. This type of production produces polyalkenamers which are temperature-stable at 180 C.
