Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a synthetic polymer composition for forming interpenetrating polymer networks. SOLUTION: The composition comprises: (a) a first multifunctional synthetic polymer having a core and m functional groups X; (b) a multifunctional crosslinker having n functional groups Y; and (c) a tensile strength enhancer, wherein when (a), (b), and (c) are mixed together, interpenetrating networks are formed by a reaction of a functional group X with a functional group Y via formation of a covalent bond Z; and then the interpenetrating polymer networks formed in this manner has the tensile strength of at least 10% of cyanoacrylate when measured under the same condition. In a preferable embodiment, the composition includes the tensile strength enhancer and the synthetic polymer with two activated multifunctional groups. COPYRIGHT: (C)2010,JPO&INPIT
