Claims32
A process for preparing a water-curable silane modified alkylene alkylacrylate copolymer which comprises reacting an alkylene alkylacrylate copolymer with a silane characterized by the following formula:
- X--CH.sub.2).sub.a SiY.sub.3
- wherein
- X is SH, NH.sub.2 or ##STR16## wherein R therein is ##STR17## or C.sub.1 to C.sub.18 alkyl;
- R.sub.1 is independently hydrogen or C.sub.1 to C.sub.18 alkyl;
- a is an integer of 1 to 18;
- Y is independently hydrogen, a hydrocarbon radical of 1 to 18 carbon atoms, C.sub.1 to C.sub.18 alkoxy or --O--CH.sub.2).sub.a O--CH.sub.2).sub.a H, with the proviso that at least one of Y is other than hydrogen or hydrocarbon,
- said reaction being carried out at a temperature between about 25.degree. C. and the volatility temperature of the silane, in the presence of a catalytic amount of organo titanate catalyst.
