Preparation and Characterization of Poly(2-hydroxyethyl methacrylate) and Castor Oil Based Uralkyds Interpenetrating Polymer Networks
There is a growing interest in the development polymers based on renewable resources1-2. Polyurethanes constitute a kind of materials that can vary from rubbery to glassy thermoplastics from linear polymers to thermoset. This versatility can be further controlled in terms of processing and composition to fulfil a great versatility that permit the manufacturing of products ranging from expanded ...
متن کاملInterpenetrating Polymer Networks (IPN
Interpenetrating polymer network (IPN) refers to a type of elastomer in which two chemically distinct networks coexist, ideally having a structure that is homogeneous down to the segmental level [1]. The two components are present as co-continuous, interlocking networks (catenanes). This co-continuity can be achieved by kinetic retention of an initially miscible mixture of the monomers used to ...
متن کاملSmall angle neutron scattering by interpenetrating polymer networks of poly(carbonate-urethane) and polyvinyl pyridine
Small-angle neutron scattering experiments by interpenetrating networks of poly(carbonate-urethane) and polyvinyl pyridine reveal that there is some degree of microphase separation at all compositions, possibly, in some compositions, into a bicontinuous phase. The domain size is some undred angstroms in the samples with only one glass transition
متن کاملTribological performance of polymethyl methacrylate as an aviation polymer
Polymethyl methacrylate (PMMA) is one of the most popular synthetic polymers in aircraft windshields as an alternative to glass, due to its lightweight, high transparency and impact-resistant characteristics. The erosion behavior of PMMA is critical when used as an alternative to glass in an aircraft windshield. This paper presents experimental data on the effects of particle size, velocity and...
متن کاملSynthesis and Characterization of Biodegradable Semi-Interpenetrating Polymer Networks Based on Star-Shaped Copolymers of ɛ-Caprolactone and Lactide
In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...
