preparation example Construction
[0076] Exemplary core-shell polymers and their preparation are described in US Patent No. 4,778,851 (Henton et al.). Commercially available core-shell polymers are available, for example, under the tradename PARALOID (e.g., PARALOID EXL 2600 and PARALOID EXL 2691) from Rohm & Haas Company (Philadelphia, PA) and under the tradename KANE ACE (e.g., KANE ACE MX120 and KANE ACE MX153) were obtained from Kaneka (Belgium).
[0077] Other toughening agents can be prepared by reacting an amino-terminated material or a carboxyl-terminated material with an epoxy resin to produce an adduct that is phase-separated from the other components of the cured adhesive composition. Suitable amino-terminated materials that can be used to prepare such tougheners include, but are not limited to, those commercially available under the trade designation DYNAMAR POLYETHERDIAMINE HC 1101 from 3M Corporation, Saint Paul, MN. Suitable carboxy-terminated materials include carboxy-terminated butadiene-acry...

[0149] Metal sheet oiled
[0150] Using the density data from the appropriate oil MSDS, oiled steel panels (Metal Press to use as-is). Using the clean fingertips of a nitrile glove, carefully spread the oil evenly over the surface. Once the surface is covered, store the metal plate at room temperature for 24 hours before use.

[0159] Preparation Example 1-5: Preparation of Reactive Liquid Modifier
[0160] Reactive liquid modifiers were prepared by weighing each of the three ingredients shown in Table 3 into a three-neck round bottom flask. A stirrer was added to the flask and the flask was purged with nitrogen. The flask was heated to 110° C. in an oil bath under reflux and nitrogen for at least 4 hours. The resulting product was vacuum distilled for 30 minutes.
