ABSTRACT OF THE DISCLOSURE The instant invention is directed to a polyol ? a molecular weight of 2,000 to 8,000 which is ?ially suited for use in the production of heat sealable forms, comprising the adduct obtained by sequentially reaction: (a) a polyhydroxyl initiator, with a functionality of 2 to 5 and a weight average molecular weight as determined by gel permeation chromatography of from 62 to 200; with (b) 10 to 90%, by weight, based on the total oxide present in (b) + (c) + (d), a first alkylene oxide; and sub- sequently reacting the product with (c) 10 to 80%, by weight, based on the total oxide present in (b) + (c) + (d), 4,4,4-trichloro-1,2-epoxybutane and/or epihalohydrin; and subsequently reacting the product with (d) 10 to 60%, by weight, based on the total oxide present in (b) + (c) + (d), a second alkylene oxide.
