This article is focused on design issues concerning the long spindle used to grind the internal pipe diameters. In the article an example of spindle design for an internal pipe diameter grinder can be found to process 11 m long pipes with external di

The low-polar polymerization of isobutylene (IB) in the presence of BCI3 was carried out in CH2Cl2 ([IB]=7 mol/l) at -78, -20 and +20°C in the presence of vinyl chloride/2-chloropropene (VC/2CP) copolymer, representing PVC resin enriched in structur

Thermal dehydrochlorination of syndiotactic poly(vinyl chloride) sequences initiated by structural defects possessing chlorine atoms bound on tertiary carbon atoms (branched structures) was theoretically studied on the low-molecular-weight models usi

The effect of moisture in vinyl chloride (VC) on its polymerization initiated with tert-butyllithium was investigated. The conversion curves thus obtained and the dependences of molecular weights of isolated products show that within range 6.5 - 80 p

Low-molecular-weight plasticizers are commonly used in the production of plasticized PVC. However, they readily migrate to the surface of the product, which results in the deterioration of physical properties and contamination of environment. This dr

The dehydrochlorination of isotactic, low-molecular-weight models of PVC, dimers to pentamers, was studied using the semiempirical MNDO method. The results obtained lead to the conclusion that the thermal dehydrochlorination of PVC can occur through

It has been surprisingly discovered that an initiator system based on PVC/SUCl4 produces bulk polymerization of isobutylene even under conditions, when a mixture of isobutylene and SnCl4, in the absence of a polar medium, does not polymerize. The PVC

The polymerizations of isobutylene initiated with the system tert-butyl chloride (t-BuCl)/SnCl4 and carried out in CH2Cl2 at −20°C and −78°C were investigated. The results obtained demonstrate that the presence of t-BuCl in the polymerizing sys
