An Interpenetrating polymer network (IPN) is a polymer comprising two or more networks which are at least partially interlaced on a polymer scale but not covalently bonded to each other. The network cannot be separated unless chemical bonds are broken.The two or more networks can be envisioned to be entangled in such a way that they are concatenated and cannot be pulled apart, but not bonded to each other by any chemical bond. IUPAC definition Note: A mixture of two or more pre-formed polymer networks is not an IPN.

| - An Interpenetrating polymer network (IPN) is a polymer comprising two or more networks which are at least partially interlaced on a polymer scale but not covalently bonded to each other. The network cannot be separated unless chemical bonds are broken.The two or more networks can be envisioned to be entangled in such a way that they are concatenated and cannot be pulled apart, but not bonded to each other by any chemical bond. IUPAC definition Interpenetrating polymer network (IPN): A polymer comprising twoor more networks which are at least partially interlaced on a molecular scalebut not covalently bonded to each other and cannot be separated unless chemicalbonds are broken. Note: A mixture of two or more pre-formed polymer networks is not an IPN. Semi-interpenetrating polymer network (SIPN): A polymer comprising one ormore networks and one or more linear or branched polymer(s) characterized by thepenetration on a molecular scale of at least one of the networks by at least someof the linear or branched macromolecules. Note: Semi-interpenetrating polymer networks are distinguished frominterpenetrating polymer networks because the constituent linear or branchedpolymers can, in principle, be separated from the constituent polymer network(s)without breaking chemical bonds; they are polymer blends. Sequential interpenetrating polymer network: Interpenetrating polymer networkprepared by a process in which the second component network is formedfollowing the formation of the first component network. Sequential semi-interpenetrating polymer network: Semi-interpenetratingpolymer network prepared by a process in which the linear or branchedcomponents are formed following the completion of the reactions that lead tothe formation of the network(s) or vice versa. Simply mixing two or more polymers does not create an interpenetrating polymer network (polymer blend), nor does creating a polymer network out of more than one kind of monomers which are bonded to each other to form one network (heteropolymer or copolymer). There are semi-interpenetrating polymer networks (SIPN) and pseudo-interpenetrating polymer networks. To prepare IPNs and SIPNs, the different components are formed simultaneously or sequentially.
- شبكة البوليمر المتداخلة (IPN) هي مكثور (بوليمر) يتكون من اثنتين فأكثر من الشبكات المتداخلة جزئيًا على مقياس من البوليمر وغير مترابطة برابط تساهمي فيما بينها. ولا يمكن فصل هذه الشبكات إلا بتكسير الروابط الكيميائية.ويمكن تصور أن هاتين الشبكتين (فأكثر) بينهما تشابك يصل لدرجة التسلسل ولا يمكن الفصل بينهما، على الرغم من عدم وجود أي رابط كيميائي يجمع بينهما. ومجرد الخلط بين اثنين أو أكثر من البوليمرات لا يمكن أن يُنشئ شبكة بوليمر متداخلة (خليط بوليمر)، ولا يعمل على إنشاء شبكة بوليمر لأكثر من نوع واحد من المونومير التي ترتبط فيما بينها لتكون شبكة واحدة (البوليمر المختلط أو البوليمر المشترك). هناك شبكات بوليمر شبه متداخلة (SIPN) وهناك شبكات بوليمر زائفة التداخل. ولإعداد شبكة بوليمر شبه متداخلة وشبكة بوليمر زائفة التداخل، يتم تشكيل المكونات المختلفة في آن واحد أو على التوالي.
- Una xarxa polimèrica interpenetrada (o IPN, de l'anglès interpenetrating polymer network) és un tipus de polímer. És format per dues o més xarxes que estan com a mínim parcialment entrellaçades a escala polimèrica, però sense formar enllaços covalents entre elles.
