Abstract: Disclosed herein are copolymers comprising at least one block comprising C8-C12 olefin-derived units, at least one block comprising C4-C6 olefin-derived units, and at least one block comprising C5/C10 olefin-derived units, wherein each block has a number average molecular weight of at least 300 g/mole and two glass transition temperatures (Tg). The olefin block copolymers are formed by combining a first olefin with a catalyst at least a first stage to form a first olefin block, and combining a second olefin with the same or different catalyst in at least a separate stage to form a second block. The copolymers are useful as tackifiers in adhesive compositions and in films.

The polymer blend has a melt viscosity of about 900 cP to about 19,000 cP. When subjected to Temperature Rising Elution Fractionation, the polymer blend exhibits a first fraction that is soluble at −15° C. in xylene, the first fraction having an isotactic (mm) triad tacticity of about 70 mol % to about 90 mol %; and a second fraction that is insoluble or less soluble than the first fraction at −15° C. in xylene, the second fraction having an isotactic (mm) triad tacticity of about 85 mol % to about 98 mol %. The tackifier has a softening point, as determined by ASTM E-28, of about 85 to about 135° C. and an aromaticity of about 2 to about 12 mol % aromatic protons.

Abstract: Described herein are hydrocarbon polymer modifiers for use in various applications. The hydrocarbon polymer modifier comprises a cyclic component, and has a glass transition temperature and Mn defined by the following two equations: (1) Tg≥95−2.2*(% H Ar), and (2) Tg≥−53+(0.265*Mn); an aromatic proton content (% H Ar) of from 12 mole % to 19 mole %; and an Mn of from 300 g/mole to 450 g/mole, wherein Tg is glass transition temperature as expressed in ° C. of the modifier, the % H Ar represents the content of aromatic protons in the hydrocarbon polymer modifier, Mn represents the number average molecular weight of the hydrocarbon polymer modifier, and the cyclic component is selected from the group of a distillation cut from a petroleum refinery stream, and/or C4, C5 or C6 cyclic olefins and mixtures thereof. Further, the hydrocarbon polymer modifier may be characterized by a Tg of from 70° C. to 95° C. and/or a z-average molecular weight (Mz) of the hydrocarbon polymer modifier of less than 1000 g/mole. The hydrocarbon modifiers are particularly useful in high Tg applications where low molecular weight resin is desirable.
