Poly(ethylene-butylene) (meth)acrylates and related compositions
View Patent ↗A composition comprising a polymer according to Structure 1 wherein R is H, Me, Et or C 6 H 5 ; R′ is H or Me; n is a number from 1 to 100; and Z is a number from 1 to 3; f is a number from 1 to 5, with f=1 if B is nothing; A is residue of a hydrogenated polybutadiene backbone; and B nothing or it is a difunctional organic linking group is disclosed. The composition can be cured and used in a wide range of articles such as a photopolymer printing plate, sealant, caulk, encapsulent, road marking paint, photoresist, binder, impact modifier, polymer modifier, oxygen or water vapor barrier coating, conformal coating, solder mask, pigment dispersion, stereolithograph, laminating resin, grafted co-polymer, composite, optical fiber coating, paper coating, metal coating, glass coating, plastic coating, wood coating, waterproofing material, electrical insulating material, automotive belt or hose, tire, engine mount, gasket, golf ball core, and rubber roll.
1. A process of preparation of a composition comprising one or more (meth)acrylate-terminated, hydrogenated polybutadiene resins which comprise (alkylene oxide) groups and optional linking groups between the (alkylene oxide) groups and the terminal (meth)acrylate groups; comprising the steps of:
(A) alkoxylation reaction of a hydrogenated hydroxyl-functional polybutadiene resin with an alkylene oxide; and
(B) transesterification reaction of the resulting alkoxylated resin of step (A), with a low molecular weight (meth)acrylate.
