[0240] 1. Preparation of PBPE

[0241] Hafnium metal complexes using polyvalent aryloxyether catalysts produced seven PBPEs. Catalyst A is a hafnium metal complex of a polyvalent aryloxyether catalyst, which is [[2',2"'-[(1R,2R)-1,2-cyclohexanediylbis(methylene oxide -κO)]bis[3-(9H-carbazol-9-yl)-5-methyl[1,1'-biphenyl]-2-hydroxyl-κO]](2-)]dimethyl hafnium.

[0242] Catalyst B is a hafnium metal complex of a polyvalent aryloxyether catalyst, which is [[2',2"'-[1,3-propanediylbis(oxyl-κO)]bis-{3-[ 9H-3,6-bis-(1,1-dimethylethyl)-carbazol-9-yl]}-5'-fluoro-5-(1,1,3,3-tetramethylbutyl )-[1,1'-biphenyl]-2-hydroxyl-κO]](2-)]dimethyl hafnium.

[0243] Table 1 below provides the names and structures of Catalyst A and Catalyst B.

Abstract

The present invention provides a composition. In one embodiment there is provided an adhesive composition comprising A) a propylene-based plastomer or elastomer (PBPE) comprising up to 10 wt% of units derived from ethylene and have (i) a Koenig B-value of less than 1.0, (ii) a total unsaturation per mole of propylene of 0.01% to 0.03%, (iii) a density of 0.870 g / cc to 0.890 g / cc, (iv) at A melt viscosity of 800 mPa.s to 11,000 mPa.s at 177°C and (v) a weight average molecular weight of 20,000 to 50,000 g / mol; B) a tackifier; and C) a wax.

Description

[0001] References to related applications [0002] This application claims priority to US Provisional Application Serial No. 62 / 040,123, filed August 21, 2014, the entire contents of which are hereby incorporated by reference to the extent that language is not inconsistent with this application. technical field [0003] The present invention relates to compositions suitable for adhesive applications and in particular hot melt adhesive applications. Background technique [0004] A general rule of thumb for compositions used in traditional hot melt adhesive (HMA) formulations is 1 / 3 polymer, 1 / 3 tackifier, and 1 / 3 wax. Due to the shortage and increasing cost of tackifiers, there is a growing market demand for HMA formulations with higher polymer content and less tackifier. However, reducing the amount of tackifier and increasing the amount of polymer has the effect of degrading adhesion and increasing the setting time of the HMA composition when using traditional polymers li...
