Abstract
The present invention relates to an adhesive comprising a thermoplastic polyacrylated glycerol polymer, water, and a cross linker that is reactive with the polyacrylated glycerol polymer. This adhesive is useful in the formation of cellulosic products including oriented strand board (OSB), particle board, oriented structural straw board, chipboard, plywood, laminated veneer lumber (LVL), pressed wood, glued laminated timber (glulam), cross-laminated timber (CLT), and other wood products. Methods of producing the adhesive and cellulosic products are also disclosed.
