preparation Embodiment 1
[0091] In this preparative example a polyetheramine-epoxysilane adduct is prepared. 10 g of Voranol CP450, 2.36 g of KH560 and 0.57 g of Jeffamine D-400 were separately added to a flask equipped with an addition funnel, reflux condenser and mechanical stirrer and stirred well until a homogeneous liquid phase was formed. The contents were heated at 50°C for 4 hours, during which time the reaction was monitored for IR epoxy peaks with an FT-IR spectrophotometer. This product was labeled Adduct 1.
preparation Embodiment 2
[0093] In this preparative example a polyetheramine-epoxysilane adduct is prepared. 10 g Voranol CP450, 1.68 g KH560, 0.9 g DER 383 and 0.57 g Jeffamine D-400 were separately added to a flask equipped with addition funnel, reflux condenser and mechanical stirrer and stirred well until a homogeneous liquid phase was formed. The contents were heated at 50°C for 4 hours, during which time the reaction was monitored for IR epoxy peaks with an FT-IR spectrophotometer. This product was labeled Adduct 2.
