Abstract
Abstract A hot melt adhesive composition comprising; (i) 50 to 5 percent by weight of a butene-1 polymer; (ii) 50 to 95 percent by weight of a tackifying resin; with the weight percentages of (i) and (ii) being based upon their combined weight; (iii) 0.01 to 1 parts by weight of a nucleating agent; (iv) up to 2 parts by weight of a stabilizer; (v) up to 30 parts by weight of a plasticizer; and (vi) up to 30 parts by weight of a wax, the parts by weight of (iii) to (vi) being based on 100 parts by weight (phr) of (i) and (ii) can readily be formulated with an open time tailored to an intended use.
