Abstract:
A crosslinking agent for use in the production of a highly water-absorbing polymer comprising a polymerizable compound having a carbon-carbon double bond or a salt thereof,said crosslinking agent comprising a polyallyl ether compound having at least two allyl groups and at least one hydroxyl group derived from a glycidyl group, and said polyallyl ether compound being: (A-1) a polyallyl ether compound having at least two allyl groups and at least one hydroxyl group derived from a glycidyl group, and having no oxyethylene chain, and/or (A-2) a polyallyl ether compound having at least two allyl groups and at least one hydroxyl group derived from a glycidyl group, and having at least one oxyethylene chain, which is an addition product between an ethyleneglycol diglycidyl ether compound of the general formula: GO-(CH2CH2O)n-G â€ƒwherein G is a glycidyl group, and n is a whole number of at least 1, and trimethylolpropane diallyl ether.
