Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

Journal of Applied Polymer Science, Volume 143, Issue 20, May 20, 2026.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...

Poly(L‐Lactide‐Co‐ ε ‐Caprolactone)/glass Fiber Composites: Toward Improved Mechanical Properties of Polylactide‐Based Composites

Polymer Composites, Volume 47, Issue 9, Page 7812-7825, 10 May 2026.
Enhanced impact strength in PLLA‐based composites via ε‐caprolactone incorporation in the matrix. ABSTRACT Inherent brittleness and limited toughness of polylactide (PLA) restrict its use in high‐performance applications. To overcome these limitations, poly(L‐lactide) (PLLA) is often blended with more ductile thermoplastics or chemically modified ...

Oxyluminescence of polyamide 12

Polymer Degradation and Stability, 1994
Abstract The oxyluminescence of unstabilised samples of polyamide 12 was studied in the temperature range 80–250°C. The chemiluminescence intensity was first recorded at constant oxygen pressure and temperature. The kinetic curves reveal the existence of two kinetic stages.

Fusion bonding of polyamide 12

Polymer Engineering & Science, 2001
AbstractThe strength of fusion bonds between polyamide 12 plaques has been investigated as a function of processing conditions, using the double cantilever beam geometry to measure the mode I critical strain energy release rate, Gc. Bonding was carried out using an instrumented press, which allowed systematic variation of the bonding time, the holding ...

Thermoplastic Elastomer Based on Epoxidized Natural Rubber/Polyamide-12 and Co-Polyamide-12 Blends

Advanced Materials Research, 2012
Thermoplastic elastomers based on blending of epoxidized natural rubber with 30 mol% epoxide (ENR-30) with polyamide-12 (PA-12) (i.e., ENR-30/PA-12) and blending of ENR-30 with co-polyamide-12 (ENR-30/CO-PA-12) were prepared by dynamic vulcanization technique. It was found that the dynamically cured ENR-30/PA-12 blends exhibited higher tensile strength,

One‐pot synthesis of polyamide 12,T–polyamide‐6 block copolymers

Journal of Polymer Science Part A: Polymer Chemistry, 2011
AbstractPolyamide 12,T–polyamide‐6 (PA‐12,T–PA‐6) block copolymers were synthesized by anionic polymerization of caprolactam using a PA‐12,T macrocoinitiator (McI). PA‐12,T McI and its precursors are soluble in molten caprolactam allowing for both the McI step‐growth polymerization and anionic polymerization to be performed in one‐pot.

Relaxational properties of plasticized polyamide-12

Polymer Science U.S.S.R., 1979
The dielectric relaxation characteristics of polyamide-12 (polydodecalactam), plasticized by sulphonamides of the type RSO2NHC4H9 (where R is phenyl, β-naphthyl, 3-pyridyl or 8-quinolyl), were studied over a wide range of temperatures and frequencies (−100°C to + 100°C and 0.5–200 kHz). The glass temperature and relaxation time were determined, and the

Viskositäts‐molekulargewichts‐beziehung für polyamid‐12

Die Makromolekulare Chemie, 1977
AbstractLight‐scattering and viscosity measurements were performed on dilute solutions of polyamide‐12 in 1,1,1,3,3,3‐hexafluoro‐2‐propanol at 25°C. The [η]‐M̄w relationship was determined to be [η]=8,43·10−4·M̄w0,68 dl g−1.
