Tackifiers and a process to obtain tackifiers
摘要:
Novel tackifier resins having a M.sub.n of 5,000 or less and a T.sub.g of 0.degree. C. or above are produced by combining a metallocene catalyst with an alpha-olefin and a cyclic monomer. New adhesives are produced by blending the novel tackifier with a base polymer.
