| titleOfInvention | Unbalanced multi-block SBS and method for the preparation thereof |
| abstract | The present invention relates to the unbalanced multi-block styrene-butadiene-styrene (SBS) and provides the copolymer represented by the following structure, mB1*S1−lB2−S2−sB3,n wherein B is a butadiene block, S is a styrene block, l, m, s are the relative size among the blocks (i.e., large size, middle size, and small size, respectively), and * is the tapered block between mB1 block and S1 block (i.e., random copolymer of a kind). They have to satisfy the following related expressions.n n0.01lB2≦mB1≦0.5lB2 and 0.01mB1≦sB3≦0.5mB1 a)n n0.5S1≦S2≦1.5S1 b)n n5%≦*%≦25% c)n In the related expression, the value of B1 and S1 include tapered block for the sake of convenience, and * % is the random styrene content in all the styrene in SBS. nn The unbalanced multi-block SBS of this invention exhibits excellent processability in the preparation of hot-melt adhesives, reducing processing hours. It also exhibits good adhesive properties such as initial loop tack, 180° peel strength, and holding power, and it has a normal level of heat resistance. |
