Dear Mr, MsThank you for your courteous answer.I am looking for transparent and neutral polymer soluble in isopropyl (and possibly in ethyl) alcohol for using in histopathology practice.For all I know poly(butylmethacrylate) or polyvinyl butyral meets these requirements.It would be desirable for me to obtain for the first stage a sample of poly(butylmethacrylate) or polyvinyl butyral - approximately 100 g - and information about it's chemical and phisical properties. One of the important requirements is absence of microscopical dust contaminants and suitable for glass gluing.If validation of suitability will be successful I need for the second stage of development several kg (~3) of poly(butylmethacrylate) or polyvinyl butyral to test more carefully the suitability for the above mentioned purpose.I'll be very appreciated if you can informed me about the possibility of obtaining a sample of poly(butylmethacrylate) or polyvinyl butyral (approximately 100 g) and (if I'll move to the second stage) up to several kg.Please inform me about your prices (including shipping to Israel) and the method of payment.Sincerely yoursMichael KoganEye Pathology LaboratoryDept of OphthalmilogyHadassah Univ HospP.O.B. 12000, Jerusalem, 91120, Israelkogen@hadassah.org.il
