1. Kinetics, Thermodynamics and Mechanisms of the Polymerization Processes
   
   a. Established identical reactivities of ions and ion-pairs in cationic ring-opening polymerization and explained this general phenomenon in time when the paradigm of higher reactivity of ions (free) was generally accepted. This observation is the most important mechanistic and kinetic feature of the cationic ROP.
   
   b. Discovered equilibrium between covalent and ionic species in polymerization and developed on this basis kinetic treatment of polymerizations with temporary (reversible) deactivation of active species. Gave the first in macromolecular chemistry kinetic treatment of the covalent species - ion-pairs interexchange by using the "temperature jump" kinetic technique. This conceptual approach of fast exchange between dormant and active species (observed also independently by Prof. Saegusa, mostly for oxazolines) has later been used for understanding mechanisms of vinyl cationic and free radical (so called "controlled") polymerization as developed by K. Matyjaszewski , former Ph.D. student of Prof. Penczek.
   
   c. Developed general kinetic theory of the chain transfer to polymer with chain rupture and nomograms allowing (for the first time) determination of the ratio of rate constants of propagation to transfer from the dependence of polymer dispersity index on monomer conversion. This is a general treatment that is applicable to any polymerization. It was used to relate the selectivity parameter (kp/ktr ) to structure of active centres.
   
   d. Applied for the first time in macromolecular chemistry dynamic NMR for studies of the ultra fast reactions ( rate constants ~ 108 M s-1) of exchange between various ionic forms of active species .Established on this basis general mechanism of cyclic acetals polymerization (dismission of the ring expansion mechanism proposed by others)
   
   e. Developed novel catalytic systems (several patents) for cyclic acetals polymerization; on this basis large scale technology has been organized in Poland. Licenses have been sold to several countries.
   
   
2. Synthesis of new polymer structures
   
   a. Discovered conditions of anionic copolymerization of elemental sulfur with cyclic sulphides, leading to stable, soluble products (up to 96% of sulfur content) .Paper published in NATURE.
   
   b. Developed of a new general method of synthesis of soluble, highly branched (star like) polymers by reaction of macromolecular alcohols with bicyclic compounds (e.g. diepoxides).
   
   c. First application of the highly efficient dihydrophilic, block copolymers, containing polyphosphates blocks, in controlled crystallization of inorganic compounds.
   
   d. First synthesis of high molar mass models of the bare chains of DNA and teichoic acids (TA - poly(glycerolphosphates) PGPH) by ring opening polymerization.
   
   e. Established specificity of interactions of PGPH with Ca²⁺ and Mg²⁺ (in cooperation with molecular biologists). PGPH were prepared either by ROP or by novel process of transesterification of H-dialkylphosphonates followed by oxidation.
   In this work the long time controversy in biosciences has been solved. Pure models of TA allowed establishing that (surprisingly) the apparently "larger" distance between phosphate groups (in 1,3 units) are specific for cation with smaller ionic radius. This stems from specific conformation of polyphosphate chains, established in these works.
